Feature
-------

Summary
-------
Support upto 65536 quota configurations per volume.

Current status
--------------
Current implementation of Directory Quota cannot scale beyond a few
hundred configured limits per volume. The aim of this feature is to
support upto 65536 quota configurations per volume.
Detailed Description
--------------------
TBD
Benefit to GlusterFS
--------------------
More quotas can be configured in a single volume thereby leading to
support GlusterFS for use cases like home directory.
Scope
-----
### Nature of proposed change
- Move quota enforcement translator to the server
- Introduce a new quota daemon which helps in aggregating directory
consumption on the server
- Enhance marker's accounting to be modular
- Revamp configuration persistence and CLI listing for better scale
- Allow configuration of soft limits in addition to hard limits.
### Implications on manageability
Mostly the CLI will be backward compatible. New CLI to be introduced
needs to be enumerated here.
### Implications on presentation layer
None
### Implications on persistence layer
None
### Implications on 'GlusterFS' backend
None
### Modification to GlusterFS metadata
- Addition of a new extended attribute for storing configured hard and
soft limits on directories.
### Implications on 'glusterd'
- New file based configuration persistence
