Add process log command

[antho1404]

Add the command process:log in order to display all the executions that match a specific process and display useful information

Here is an example of a process log

[execute-task-x] - H74Qqq8nT5JZ9GSJmuSWLN5benWZPkUb5pYcvQLsoZX - serviceA - taskX
        inputs:  { message: 'event' }
        outputs: { value: 'serviceA#taskX' }

[toTaskY] - DTjy36ApV5YVbyXm67iWeAsD9uCbZETcPL1TbUPwHeYJ - serviceB - taskY
        inputs:  { inputA: 'serviceA#taskX' }
        outputs: { res: 'serviceA#taskX => serviceB#taskY' }

What do you think about this log? Any idea of how to improve it?

I like logs :)

service "serviceB" - instance DTjy36ApV5YVbyXm67iWeAsD9uCbZETcPL1TbUPwHeYJ execute "taskX"
        inputs:  {
          inputA: 'taskX' 
        }
        outputs: {
           res: 'taskX => taskY'
        }
recived from `Map`...

Above one is just a bad proposal, but here are a few things to consider:

• the first line with seperated with - doesn't give us an option for adding things later. Maybe use more description? What do you think about the service name first?
• pretty print inputs and outputs (multiple lines)
• I don't understand the notation of outputs, what exactly it means
• can we put information about the receiving node (the type of node in that case Map) and maybe print the map to show the input mapping
• just a thought about the API (not related to logs). The execution has StepID fields which I feel is not intuitive at all (don't a have a better name for now).

the first line with seperated with -

I agree that's not really nice but I would love to have this log concise. I can put some \t as separator

What do you think about the service name first?

You could have multiple tasks in your process that uses the same service so it's more "unique" to have the node like that we can see quickly what step has been processed.

pretty print inputs and outputs

I even wanted to put all that in one line only, it might be a lot of logs.

I don't understand the notation of outputs, what exactly it means

This is the end of execution for a task so there are the inputs for this task and the outputs/result of the task

can we put information about the receiving node

This only log the results of the executions as filters and map are internal and there is no api to have these events. Also, the receiving node is displayed, that's the one in [] eg: [execute-task-x]
