Problem: Some directory vxattrs (e.g. ceph.dir.pin.random) are governed by information that isn't necessarily shared with the client. Add support for the new GETVXATTR operation, which allows the client to query the MDS directly for vxattrs. When the client is queried for a vxattr that doesn't have a special handler, have it issue a GETVXATTR to the MDS directly. Solution: Adds new getvxattr op to fetch ceph.dir.pin*, ceph.dir.layout* and ceph.file.layout* vxattrs. If the entire layout for a dir or a file is being set, then it is expected that the layout be set in standard JSON format. Individual field value retrieval is not wrapped in JSON. The JSON format also applies while setting the vxattr if the entire layout is being set in one go. As a temporary measure, setting a vxattr can also be done in the old format. The old format will be deprecated in the future.
