Don't install ReplicationStatusModule when replication lag is disabled
The ReplicationStatusModule is responsible for scanning *all* the
projects and checking their replication lag 'refs/multi-site/version'
against the global-refdb.
If the replication lag isn't enabled, there is no point to run the
expensive job of scanning all repos, saving precious CPU cycles and
avoiding the associated disk I/O and global-refdb calls.
