> Ratis requires {{RaftGroupId}} to be a UUID. We need to generate this ID from
> the {{OMServiceID}} so that it is consistent across all the OM nodes in a HA
> service.
> Currently, we expect {{OMServiceId}} to be a 16 character string so that it
> can be converted to a UUID. But {{OMServiceID}} is a user configurable
> setting. Hence we cannot force users to input a 16 character string.
> One option is to hash the \{{OMServiceID}} string then truncate to UUID
> length and use that to generate the UUID.
