* hard and soft limits are persisted in xattrs of the
inode. Associating limits with inode instead of maintaining as a
global list helps us to scale better.
* quotad-aggregator acts as a special client to provide cluster view
through an rpc program. Quota enforcer loaded on brick uses this to get
aggregated directory sizes. Aggregated sizes are cached for a
timeout period in in-memory inode contexts.
