Support multiple replicas for sdo-owner-services

[bmpotter]

The roadblock right now is we are using SDO's reference implementation of OCS, which saves the "DB" info in files in a persistent volume. If multiple instances of OCS are running, we could get file corrupition (w/o locking).

The FIDO release of SDO (1H21), the equivalent of OPS will have a JDBC interface to its persistence, so we can plug in our own DB (postgresql) and don't have to implement our own OCS. This will be by far the easiest/best way to support multiple replicas of the SDO services.
