Add version command

[dfarr]

It would be nice to see the version of resonate I have installed locally.

resonate --version

The version is tied to the git tag and can be set via build flags in our release pipeline, we should assert that the git tag matches the version in our release pipeline.

• set tag in release pipeline
• assert git tag matches resonate --version

Version can be derived from the Git Tag, but not necessarily required for the mvp.
