pgoutput: Raise an error for missing protocol version parameter.

Browse Source 
Currently, we give a misleading error if the user omits to pass the
required parameter 'proto_version' in SQL API
pg_logical_slot_get_changes() or during START_REPLICATION protocol
message. The error raised is as follows which indicates that the wrong
version is passed.
ERROR:  client sent proto_version=0 but server only supports protocol 1 or higher
