extsvc/github: remove log15 usage (!35759) · Merge requests · Administrator / sourcegraph

Administrator requested to merge remove-log15 into main May 19, 2022

Created by: bobheadxi

This is a follow-up to https://github.com/sourcegraph/sourcegraph/pull/35516 to completely remove log15 usage from extsvc/github - I realized I missed quite a few spots as I was re-reviewing the PR for GitStart.

I decided not to parameterize the GitHub V4 loggers yet to minimize the change for now.

Test plan

sg start

and tests pass
