Merge branch 'process-commits-using-sidekiq' into 'master'

Processing Commits Using Sidekiq

This moves the code  of `GitPushService#process_commit_messages` into a separate Sidekiq worker. This allows processing of commits to happen in parallel, speeding up the process. See the individual commit (messages) for more information.

Part of https://gitlab.com/gitlab-org/gitlab-ce/issues/15463
