protocol/server: do not do root-squashing for trusted clients
* As of now clients mounting within the storage pool using that machine's
ip/hostname are trusted clients (i.e clients local to the glusterd).
* Be careful when the request itself comes in as nfsnobody (ex: posix tests).
So move the squashing part to protocol/server when it creates a new frame
for the request, instead of auth part of rpc layer.
* For nfs servers do root-squashing without checking if it is trusted client,
as all the nfs servers would be running within the storage pool, hence will
be trusted clients for the bricks.
* Provide one more option for mounting which actually says root-squash
should/should not happen. This value is given priority only for the trusted
clients. For non trusted clients, the volume option takes the priority. But
for trusted clients if root-squash should not happen, then they have to be
mounted with root-squash=no option. (This is done because by default
blocking root-squashing for the trusted clients will cause problems for smb
and UFO clients for which the requests have to be squashed if the option is
enabled).
* For geo-replication and defrag clients do not do root-squashing.
* Introduce a new option in open-behind for doing read after successful open.
