Main changes in robinhood 3.1
===================

* Ingest rate optimizations: up to x10

* New plugin type: action schedulers
   These plugins make it possible to reorder policy actions, or smooth 
policy execution.
   In this release, two of such plugins are provided: 
`common.max_per_run` and
   `common.rate_limit`.

* Policy optimizations:
     - Improved pre-filtering: convert all policy rules to SQL for better
       pre-filtering.
     - Configurable attribute matching before/after scheduling
       (pre/post_sched_match parameters).

* FS scan: make it possible to restrict scan to several directories
   ('scan_only' configuration parameter).
     - Especially useful with Lustre's static DNE partitioning.

* Pre/post policy run commands

* Modeguard status manager
     - Enforce or clear permission bits on entries of the filesystem

* Fixes for Lustre 2.10
     - Note: this robinhood version does not support Progressive File 
Layouts yet

* REST API and web interface enhancements:
     - Plugin mechanism to add custom charts/fields/requests...
     - Finer access control (limit user views only to their stats)
     - All robinhood DB available through the REST API
