This implements an auto-disable feature in nova-compute, where we automatically set our service record to disabled if we consecutively fail to build a certain number of instances. While this is a very useful thing to do in general, disabling a failing compute becomes more important in the future where scheduler retries due to unknown failures may become either impossible or scoped to a single cell. Since a compute that is consistently failing will look very attractive to the scheduler, it may become a build magnet, that in the absence of retries, would effectively kill all builds in a cloud until fixed.
