Optimize secondary task recollection

[ABrain7710]

Description

Overall

• Optimized pull_request_files, pull_request_commits, and pull_request_reviews when they are recollected

Implementation Details

• When building list of repos to collect make the list contain a full_collection boolean flag so start_data_collection knows what to pass
• In AugurTaskRoutine.start_data_collection iterate through the tuples and pass the repo_git and full_collection flag to each phase
• Add full_collection flag to every phase's method arguments. This had to be done since AugurTaskRoutine.start_data_collection passes the same arguments for every phase
• Define database methods to get_secondary_data_last_collected and get prs that have been updated since a date
• Updated pull_request_files to only get pr numbers for updated prs if full_collection flag is false
• Updated pull_request_commits to only get pr urls for updated prs if full_collection flag is false
• Updated pull_request_reviews to only get pr numbers for updated prs if full_collection flag is false

Notes for Reviewers I have not tested this yet, I will change it from a draft pr to a pr when it is test

@ABrain7710 : What's the status of this one with regards to testing? Should we merge it now that we have done a release.

This is complete, but I haven't had a chance to test it yet. It is a bit of a difficult test.It is a very small change though so if it was reviewed throughly it could be probably be merged
