> HConnectionManager.isTableAvailable() the SERVER_QUALIFIER for each region, including
the offline split parent.
> In case of hbck META recovery or snapshots clone/restore an offline parent will never
be assigned (since should stay offline). In this case HBaseAdmin.waitUntilTableIsEnabled()
used by enable() and cloneSnapshot() will wait until the timeout is expired.
