#1065 client: add support for ogclient linux state

ogClient can be run in linux mode, intended for exposing some
ogServer commands when running in a linux distribution.

When connecting with a client in linux mode, do not expect a full
partition setup response. Just expect a 'status', and then accept
the connection without updating any partition information in
the database.
