Do not run multiple Git-GC jobs concurrently

The CronJob managing Git-GC was configured to start up GC-jobs, even if
the previous job was still running. This could lead to multiple Jobs
being active at the same time, if the job creation failed, e.g. if
a volume attachment failed. This produces additional load to the
API-server and to too many pods wanting to attach the same volume.

This change configures the Git-GC CronJob to forbid concurrency. If
a job is still running, when a new run is scheduled, the next job will
be skipped.
