For legacy blobs, which are Job artifacts, LFS objects, and Uploads.

On staging.gitlab.com, many files are (intentionally) missing on the
primary, so geo.staging.gitlab.com attempts to sync them every hour. We
don't want to disable retries after some maximum number, because we want
the system to automatically recover if the files ever appear. But every
hour is a bit excessive, given all retries have failed up to that point.
So this commit raises the retry time cap for legacy blobs missing on
primary from 1 hour to 4 hours.

As an aside, resources which are replicated by the Geo framework will
soon gain the automatic verification and re-verification feature. This
will eventually resync resources which were missing on the primary and
then became not missing.
