cephfs can benefit from statx. We can have the client just request caps sufficient for the needed attributes and leave off the rest. Also, recognize when AT_STATX_DONT_SYNC is set, and just scrape the inode without doing any call in that case. Force a call to the MDS in the event that AT_STATX_FORCE_SYNC is set.
