Validate commit message as part of commit queue process

As part of the migration to commit queue, pre-commit git hooks are no longer run. One of the hooks that was run validated that the commit message conformed to certain rules. With EVG-6445, we should be able to create a task that runs as part of the commit queue to validate the commit message.

As a server engineer,
I want a commit queue check to validate the commit message
So that I don't know accidentally commit with a bad message.

AC:

• A commit queue task is run that fails if the commit has an invalid message.
