Add workflow state tracking into CLI commands

Registered by Renat Akhmerov on 2020-05-18

When we run a command like:

$ mistral execution-create my_workflow input.json

It would be useful to be able to add a key that makes this command track the state of the workflow. For example:

$ mistral execution-create my_workflow input.json --track-state

This is just an example of the output. In the final version of the patch we may come up with better ideas.

Also, this tracking functionality can be implemented either as a new command (e.g. $ mistral execution-track-state) or added into "execution-get" as an optional key.

The same tracking function can be made for task and action executions.
