FSAL_CEPH: add FS cluster ID into the FSAL_CEPH filehandle Currently, the FSAL-specific portion of the filehandle is composed of a vinodeno_t, which is just an inode number and snapid tuple. In a follow-on patch we're going to allow exporting alternate, named filesystems within the same cluster. At that point, the vinodeno_t is no longer unique enough for this purpose. This patch expands the ceph_handle with a new 64-bit fscid field, that denotes the cluster ID within the filesystem. From there, teach the cluster to encode the fscid in the handle when it's available. Ceph reserves fscid 0 to denote "legacy" filesystems. If no filesystem name string is specified, or if it is a legacy filesystem, then we don't append the fscid to the handle, in order to maintain backward compatibility.
