Feature: Data migration from standalone gluster to OCS/OCP4

There is interest in the ability to migrate data out of a standalone gluster cluster (RHGS?) to OCS/OCP4. We think this is probably most appropriate as a Crane 2 usecase. John Strunk (Scribe) believes it may be possible to run a process on the standalone cluster that makes it appear as a Scribe source, that way it can be utilized like any other.
