NFS: ask for layouttypes during v4 fsinfo call
This information will be used to determine which layout driver, if any, to use for subsequent IO on this filesystem. Each driver is assigned an integer id, with 0 reserved to indicate no driver. The server can in theory return multiple ids. However, our current client implementation only notes the first entry and ignores the rest.
