LU-11213 lmv: mkdir with balanced space usage
If a plain directory default LMV hash type is "space", create
subdirs on all MDTs with balanced space usage:
* client mkdir allocate FID on MDT with balanced space usage
(space QoS code is in next patch).
* MDT allows mkdir on different MDT with its parent if it has
"space" hash type in default LMV, this is normally rejected
because mkdir shouldn't create remote directory.
