* the quota setting can happen only on 'namespace' inode.
* once set, the accounting is maintained only at the namespace level for whole tree.
* uses 'simple-quota' key to show the correct quota usage in distributed volume.
* statfs()'s response would be used to set the the volume level usage in xlator,
in setxattr() call, when done through a special mount process.
* the xlator is designed to be on brick graph, and saves only the usage of data
inside it.
* An option is provided to utilize the backend filesystem's quota feature for
'accounting', which can improve the performance.
- This PR expects backend quota to properly return `statfs()` (or `df`) output.
If `features.simple-quota.use-backend` option is set, then there wont be any
active accounting in simple-quota translator, but only `setxattr()` and
`statfs()` is handled for special keys. We expect helper function to
set 'quota-limit' and also 'namespace' xattr to aid the glusterfs process in
general to identify the entries.
