Stratis - Include new output for key-description, engine report, and cli version

[drckeefe]

In the plugin stratis.py (sos/report/plugins/stratis.py.)
Stratis (https://github.com/stratis-storage/), version 2.1.0 has a new pool encryption feature and report of the engine state, which should be added to sos.
The new additions to the stratis.py file should be:

"stratis key list" - collect a list of key descriptions
"stratis report engine_state_report" - collect the current state of Stratis' engine

Also, the version of the cli should be added.

"stratis --version" - collect the version of stratis-cli

Can definitely add these. One question, for stratis key list is there any iteration we should be doing to get detailed information for each key listed?

@TurboTurtle not at this time. We only need stratis key list output.
