Problem: add-brick command to increase replica count in an arbiter volume succeeds, causing undesirable effects like the 4th brick being loaded with the arbiter xlator, the 3rd one losing the arbiter xlator (when the brick process is restarted), arbitration logic in afr going for a toss etc. Fix: Arbiter configuration should always be a replica 3 volume (of which 3rd brick is arbiter). Hence disallow increasing replica count for arbiter volume configurations.
