glusterd/ afr: remove the readdir-failover option from rebalance process

Remove the "replicate*.readdir-failover=off" xlator option from
rebalance process' runner arguments because this is the default behaviour in
afr-v2. i.e. reaaddir failover happens only if it is a new readdir
(offset=0). 'Continuing'readdirs are always wound on the same child
where the first readdir had happened and if that child is down, the
readdir fails.

The option cannot be removed from glusterd_volopt_map because there is a
chance of ending up in peer rejected state in a heterogenous cluster
(typical upgrade scenario) due to volinfo checksum mismatch. TODO:come up with
some warning message to the user for such deprecated options if a volume
set is attempted.
