We need to extend TripleO to support per-profile RAID configuration. It was previously available as "ready state" command in tripleoclient, but relied on downstream-only patches, and hence was dropped. We need to resurrect it.
There are the following principal difference from previous code:
* Stop using "ready state" wording as everyone understands something different by it.
* Use vendor-agnostic Ironic RAID support  instead of hardcoding DRAC.
* Use a new Mistral workflow to driver the configuration.
TripleO blueprint: https://blueprints.launchpad.net/tripleo/+spec/raid-workflow
Note that the basic workflow has landed in Ocata timeframe, so there will be limited support for RAID in OSP 11.
This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.
Doesn't seem to have enough traction; software RAID is tracked in https://bugzilla.redhat.com/show_bug.cgi?id=1317918
