When the git command crashes or is aborted due to a timeout we might end
up with a leaked index.lock file in the affected repository.
This has the effect that all subsequent git operations that try to
create the lock will fail. Since Zuul maintains a separate lock for
serializing operations on a repositotry, we can be sure that the lock
file was leaked in a previous operation and can be removed safely.
