cli: simplfy gsysnc configuration command

New syntax is

 volume gsync config <master> <slave> [[!]opt [val]]

In details:

- instead of "volume gsyncd configure M S config-get-all" :
             "volume gsyncd config M S"
- instead of "volume gsyncd configure M S config-get O" :
             "volume gsyncd config M S O"
- instead of "volume gsyncd configure M S config-del O" :
             "volume gsyncd config M S !O"
- instead of "volume gsyncd configure M S config-set O V" :
             "volume gsyncd config M S O V"
