>
> In the base.py file, there is a Host class with a delete instance method.
> This method first attempts to transition the host into the maintenance
> resource state.
> The first step in this process is to transition the host into the
> prepare-for-maintenance resource state.
> A while later, the host can be transitioned completely into the maintenance
> resource state.
> In an attempt to wait for this transition to occur, the delete method has a
> timer.sleep(30) call.
> The hope is that the host will have transitioned from the
> prepare-for-maintenance resource state to the maintenance resource state
> within 30 seconds, but this does not always happen.
> We should correct this problem by putting in logic to query the management
> server for the resource state of the host. If it's in the expected state,
> move on; else, sleep for a bit and try again (up to a certain limit).
