features/shard: Support geo-rep for sharded volume

Approach:
      Shard xlator on slave side is by passed for all the fops
to geo-rep mount. So each shard on master is considered as a
separate file for geo-rep and it syncs them separately on to
slave. The extended attribute in which shard maintains the
size is also synced from master and shard on slave doesn't
calculate by itself.

Pre-requisites:
      1. If master is sharded volume, slave also should be sharded.
      2. Slave's shard configurations should be same as master.
      3. Geo-rep config of xattr sync should not be disabled.
