Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/record-reason-for-disabling-service.

Description:

I'd like to be able to define a way to log a reason when I disable a service.
This is really usefull on large deployment when you need to deal with a lot of nodes and you need a way to track why a specific service has been disabled (for example, maintenance, hw failures, and so on).

The idea is to add a column (String 255) in the services table to store a reason field.
Then we will add a new API extension to disable a service indicating a reason for that.
Then we are going to change the cinder client to support the new feature.

This feature was already handled in nova and it is better that we can port it cinder to improve debug-ability: https://blueprints.launchpad.net/nova/+spec/record-reason-for-disabling-service
