versions of TKperf and detailed changes.
Version 2.2 20180926
* Add timestamps to log messages
* Add read and write policies for megaraid devices
* Use markdown for README
* Set auto background initialization to off for megaraid devices
* Fix device number to 2 if megaraid RAID10 devices are created
* Add strip size for megaraid devices
* NVME: use correct lbaf for nvme format command
* Set correct StdyState if device did not reach steady state
* NVME: use correct interface with NVME RAID devices
Version 2.1 20151016
* Fix max rounds bug for SSD write saturation
* If the maximum rounds 1440 was reached for an SSD the number of
rounds has not been set correctly.
* Add option for specifying test round runtime
* Add 'fusion' to valid interface names, secure erasion FusionIO cards
* Use nvme format for devices with nvme interface
Version 2.0 20150121
* Refactor performance tests and devices with abstract classes
* Devices implementing the Device class can be used as test device
* Add a system package for interaction with OS command line tools like
storcli or mdadm
* Added new RAID tests, RAIDs are created automatically
* Avago or LSI devices can be tested with a specific RAID config file
* Preconditioning is done automatically on all devices in the RAID set
* Software RAID with mdadm can be tested with a specific RAID config file
* Preconditioning is done automatically on all devices in the RAID set
* Secure erase is done automatically on all devices in the RAID set
* SAS devices are tested automatically with sf_format and sg_info
* Added new TKperf logo
* Remove tkperf_dialog.sh as it is obsolete
* Fix error in tkperf-comp LAT plot
* Enhance tkperf-cmp
* Plots can be put into a subfolder and be compressed with zip
* If -g is used a PDF report is generated automatically
* Reports can be sent to an email automatically, use -m and -s
Version 1.3 20140804

Version 1.2 20131017
* Return an error if hdparm doesn't work for HDD
Version 1.1 20130117

* Description files to provide informations for devices that
cannot be checked with hdparm
* Loading from Xml is possible if plotting or reporting functions
changed and the report should be generated again
* With setup.py an installations script is provided to ease TKperf
installation
* FIO version is included in the report
* Date of test run is included in the report
* Number of jobs and number of outstanding I/Os can be changed
* Added option "refill_buffers" to circumvent any compression of
SSD controllers
* OS distribution information is included in the report
* tkperf_dialog.sh is a shell script to start a simple test script
via answering interactive questions
Version 1.0-dev 20121123
* SSD
* Tests
* Iops
* Latency
* Write Saturation
