Pass commit data to ProcessCommitWorker

This changes ProcessCommitWorker so that it takes a Hash containing commit data instead of a commit SHA. This means the worker doesn't have to access Git just to process a commit message (and other data it may use). This in turn should solve the problem of ending up with 15 000-something jobs in the process_commit queue that take forever to process.

If your commit data contains invalid utf-8 characters then the migration fails at JSON.dump(payload), the linux kernel contains such commits.

git does have encoding associated with (such( commits. just nobody thinks commits are nowadays non-utf8 :)

so data should be converted to utf-8 from source encoding.
