Ian Barwick e8ba213174 "standby register": add sanity check when --upstream-node-id not supplied ...

If --upstream-node-id was not supplied to "repmgr standby register",
repmgr defaults to the primary node as upstream node. If the local node is
available, we now double-check that it's attached to the primary,
in case the lack of --upstream-node-id was an accidental ommission.

This check is only made when the local node is available.

This behaviour can be overriden with -F/--force (though it's hard to
imagine a scenario where that would be useful).

Addresses GitHub #395.
