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.
