1. add new OP in glustersf_op_t
2. use the OP for transaction with glusterfsd (add handler for that OP in glusterfsd)
3. populate structure with members like #of files
4. the 'source' of most of statistics is posix, generate statistics like disk speed in the init() of posix and keep statistics local to posix.

some initial statistics members -

# of open files
free ram
free disk space
disk speed (one time calculation)
# of client nodes (to be filled by glusterfsd) if glusterfsd is not in path it would be 0

Each xlator should expose a statistics call which will provide statistics like # of open files via that xlator, # of clients connecting via it etc.. translator should appropriately pick the child statistics, mangle it and expose it to its caller.
