### What changes are proposed in this pull request?

Return FileNotFound when a file is being create/write. No need to refresh its metadata.
Metadata will be refreshed when file is closed.

### Why are the changes needed?

If a file is being written to, and another getStatus() comes for such file, 
this file probably has not been created in UFS. At that time,
the getStatus() thinks that this file does not exists. So the worker tries to remove its metadata and its data from cache.
ERROR logs were generated in such case.

This patch is to handle this correctly and remove such ERROR logs:

### What changes are proposed in this pull request?
Fix the array out of bound exception in presto

### Why are the changes needed?

Because we saw earlier that the LocalCacheManager swallows all exceptions, if there is an error accessing one of the cached files, the exception will be ignored. However, the offset may have changed during the failed read attempt in LocalCacheManager. When LocalCacheManager returns -1 on error and tries to reread from the lower layer storage, the offset could be out of bounds.

Regarding why this issue only appears in versions 2.9.3 and later, it's because the offset became a member variable of our target buffer starting from 2.9.3. In earlier versions it was always a local variable, so there was no compounding of offset errors.

### What changes are proposed in this pull request?

Refactor the Netty read handler of worker.

### Why are the changes needed?

The previous implementation creates a state machine per read request, instead of per channel. This implies that if two read requests are sent over the same channel, the worker would possibly use one channel to send data of different files or regions. This can lead to data corruption.

This PR proposes to use a state machine per channel, and handles channel events throughout the whole lifecycle of the channel. Things like a faulty client sending a second request over the same channel before the first request is completed, is handled gracefully with a client error.

The state transitions look like the following:

Add a test so we can monitor the vnode distribution is not too uneven. 

This test calculates the standard deviation over mean on the collection of virtual nodes assigned to physical nodes. It arbitrarily bounds it at 0.25, but ideally this number should get smaller over time as we improve hashing algorithm
and use better ways to assign virtual nodes to physical nodes.

3. In JSON format, print properties in a fixed, easy-to-read order
4. In YAML format, print properties alphabetically (since YAML specification regards property order non-significant)

For random reads, bytes read per file is not a constant any more. In spite of existing duration distribution, need a throughput distribution for better understanding of reading performance.

Also, when duration too long, grpc will receive huge size of output data. Should aggregate data points to transfer more datapoints with limited output size.

Group datapoints by threads and time slices:
Example:
```
nodeResults: {
  worker-0: {
    dataPoints: [
      data: [
        { // worker 0, thread 0, slice 0
          count: 1,
          iobytes: 33554432,
        }, { // worker 0, thread 0, other slices
          …
        }
      ], [ // worker 0, other workers
        …
      ]
    ]
    throughputPercentiles: […]
  },
  worker-1: { // other workers
    …
  }
}
```

Slice time with `--slice-size` flag, e.g. `--slice-size 1s`.

### What changes are proposed in this pull request?

Fix UFS not loaded in some cases.

### Why are the changes needed?

Fix the following error when loading `UnderFileSystemFactory`:

This was because when `Thread.currentThread().getContextClassLoader()` is null, it indicates that the class loader is actually the system class loader. If using `null` for the default class loader, it will not be able to resolve `UnderFileSystemFactory` which was already loaded by the system class loader.

Alluxio does not have a valid Block Info at this moment.

### What changes are proposed in this pull request?

return an all zero block info for fsstat

### Why are the changes needed?

No valid block info is managed by Alluxio at this moment.
Alluxio does not have 'master' node, and no block info is stored/managed by other components.

This may change in future, e.g. statfs() can gather the block info from all worker nodes.

The configuration `alluxio.user.consistent.hash.virtual.node.count` is for total virtual nodes of all workers. We need to adjust the configuration according to the number of worker nodes. However, it is difficult to determine how many virtual nodes are enough to avoid the data skew issue.

Based on this background, a better way to solve the data skew issue is to allow user to set the virtual nodes number for a worker node, but not the total virtual nodes of all worker nodes. This is what this PR does.

Don't call the ufs.close() in PageFileReader.close()

2. S3UnderFileSystem.close() will just shut down the executor held by the instance. when other threads reuse the executor, it will cause issues.

### What changes are proposed in this pull request?

1. Add an abstract representation of a worker's identity.
The new identity is the same as a `long` based identity that used to be generated by the master. It decouples the concept of an identity and the actual implementation of an identity. It also includes a version field that allows backward compatible evolution of the worker identifier.

2. A new implementation for worker identities that uses UUID.
A worker will generate its own identity instead of acquiring one from the master, unless the user explicitly specifies one in the configuration. The generated identity is then persisted in the worker's working directory, and reloaded at the next worker restart.

### Why are the changes needed?

For Dora workers, the identities are not generated by a centralized service, but by workers themselves. Therefore, we need something that provides randomness and avoids collision between workers, e.g. a UUID. The V1 parser implementation included in this PR uses a UUID as the worker identity.

### Does this PR introduce any user facing changes?

Yes, a new configuration item `alluxio.worker.identity.uuid` is added that allows a user to specify the worker identity.

### What changes are proposed in this pull request?

Split the fuse stream close() method into two individual methods:
1. Close the fuse stream
2. Release the lock

Currently no behavior changes on the close function as the function will call these two functions to achieve the same functionality as before. 

### Why are the changes needed?

When we handle some fuse operations, we sometimes want to close the stream only but want to keep the lock there, to avoid inconsistency.

By default, we build a dynamic consistent hash with the live worker list that comes from master or ETCD. Sometimes we want to build a static consistent hash ring to make sure we won't write data to other worker node when a worker node is offline temporarily (especially when other worker nodes are running out of disk space).

This PR provides allows us to build a static consistent hash ring by setting `alluxio.user.dynamic.consistent.hash.ring.enabled=false`. In this case, client will read from UFS if the worker where the specified file locate is down.

For now StressWorkerBench uses milliseconds as the smallest unit of recording. In random read, if file is very small, it is possible to have a duration <1ms. Since instant throughput = bytes read / duration, it will lead to a divide by zero error.
This PR replace millisecond-level record of a file read with a nanosecond-level approach. It also makes the following updates on StressWorkerBench:
- record file read time within `applyOperation()` function, instead of before entering or after exiting it
- wrap metrics about the `applyOperation()` function to a private class, instead of returning bytes read only
- remove getter and setters for WorkerBenchDataPoint, since all elements inside is public
- standardize the unit of output throughput, now unit is MB/s

### What changes are proposed in this pull request?

Added a manual double-safety `System.exit()` at the end of FUSE lifecycle, to be absolutely sure we exit the JVM and terminate all non-daemon & daemon threads.

Before this change, after we `alluxio-fuse umount` or `kill (not -9)`, the FUSE process may fail to quit. One reason is a non-daemon thread dangling around:
```

The JVM shutdownHook executes after the LAST non-daemon thread dies or when `System.exit()` triggers. So if some libraries we use or some thread pools of ours accidentally introduce non-daemon threads, `System.exit()` is our last resort to trigger shutdownHook.

FUSE does handle signals and exit, but there are some corner cases which don't seem to trigger that successfully. So this PR serves as the last resort.
