Add sensors for monitoring array drive and controller failures

Is this now in the master branch? Just did a svn up and did not get the hdarray unix agent.
When adding the file manually to the monitored hosts unix agent local folder the description returns with the status appended but the graphs don't update and it is listed as 'fail'

Hdarray script added.

Gah. Totally forgot about this.

Just patched it in to devel.

New patch that uses class status and sensor state

Changed to status and updated to head

I think "health" should be just "status". Boolean would sound too clinical, and health is confusing, as it's used elsewhere.

Cisco has a lot of boolean sensors too. I will need to put those here.

I am really looking forward to this feature. "Double the thanks, and double the kudos"

For right now I was thinking of creating multiple states but as I wrote it I found that part useless. I didn't see a non graphing object. Be nice to make a nagios cacti replacement. Check mk made it so easy I couldn't resist.

What do these 'sensors' return? Just boolean?

I originally thought it could be a landing place for all sorts of sensors without having to build more infrastructure for it but if you prefer I can just make it more unique.
