Patch Augur-new's task scheduling mechanism

[IsaacMilarky]

Description

• Add patches to AugurTaskRoutine to prevent one phase's changes not being reflected in subsequent phases
• Patch contributor resolution so it can parse string data better
• Phases are now defined in python functions instead of messily through an enum. The name of the phase is the name of the function and the function just returns what you want celery to run; ezpz hopefully
• Revert change to some tasks to take a repo_id instead of the repo_git string as it raised concerns about log readability.
