Add a collectoss selftest report command to the CLI

[MoralCode]

Description
This feature adds a new subcommand to the collectOSS CLI that performs a self-test of Augur

This PR is the first phase of implementing #159

Currently this checks for:

• commits (commit changes) with an empty string for the author name (indicator that cleanup is needed after bug Facade not correctly populating author name in commits table #233 on older instances)
• alembic database synchronization - CollectOSS Databases should align with the current schema. This uses the built in check feature of alembic (our database versioning tool) to compare what is in the database and what the model says should be there. (This includes a translation layer to make the output a little clearer to instance admins who arent as familiar with collectoss internals or alembic)

Sample output:

Notes for Reviewers

Still to do:

• write docs for this new CLI command
• possibly add in a pre-emptive check to look for how spread out contributor emails are in preparation for make contributor_aliases the single source of truth for contributor emails #237
• possibly hide some of the extraneous alembic logs behind the --debug flag to avoid unnecessary detail
