- Remember the uid and gid of the pid at the time of caching
the group id list.
- Next time when referring to the cache confirm that uid and gid
of that pid has not changed since. If it has, treat it like
a timeout/cache miss.
- Solves group id caching issue caused when Samba runs on gluster
FUSE mount and changes the uid/gid on a per syscall basis.

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

This change genericizes the cache mechanism implemented in commit
8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as
a client. The cache mechanism is fundamentally equivalent, with some
minor changes:
- Change cache key from uid_t to uint64_t.
- Modify the cache add logic to locate and use an entry with a
matching ID, should it already exist. This addresses a bug in
the existing mechanism where an expired entry supercedes a newly
added entry in lookup, causing repeated adds and flushing of a
cache bucket.
The fuse group cache is disabled by default. It can be enabled via
the 'gid-timeout' fuse-bridge translator option and accompanying
mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).
