Add Commit Message Table and Add Commit Messages to Facade Collection

[IsaacMilarky]

Description

• Previously Facade did not care about the commit message
• Now, we have a new table that has a unique record for each repo and commit hash with the hash's corresponding commit message
• We bulk insert the commit message data

Notes for Reviewers
Should be tested on a range of repositories before being put into production. For now this is a draft PR until we can be more confidant in it.

Signed commits

• Yes, I signed my commits.
