Workhorse git access logger frequently logs status code "0"
For git-upload-pack
and git-receive-pack
operations, the access logger for Workhorse (which uses LabKit) frequently (up to 500 times a minute) will log an illegal status code of zero for a request.

The root cause of this is currently unknown, and it only appears to happen for git requests, but it is incorrect and should be investigated further.
What's more, we may also have the same issue with our metrics, in which case this would be a blind spot in our alerting (since we don't treat these requests as being in error)
