status-get command must return an HA relationship identifier

We now support the hub-and-spoke setup with multiple relationships in one server. The HA state can be retrieved using the status-get command. The problem is, though, that the status-get result lacks an association between returned local/remote entries and the configured relationships. It makes it nearly impossible to match the returned statuses with the relationships we maintain in the Stork database. The status-get response must return identifiers of the HA relationships to enable this matching.
