Change bot detection logic and add tests around bot detection in API

Added tests for all 3 supported platforms (Github, Gitlab, and Gerrit)
around bot detection. Changed bot detection policy to check if user is
any bot, regardless of project commit is for. This allows for bots to
push in untracked projects when using strict mode as well.
