NFS: Request fh_expire_type attribute in "server caps" operation
The fh_expire_type file attribute is a filesystem wide attribute that consists of flags that indicate what characteristics file handles on this FSID have. Our client doesn't support volatile file handles. It should find out early (say, at mount time) whether the server is going to play shenanighans with file handles during a migration.
