Tear down console during unprovisioning9.1.5

Before this patch, when unprovisioning a node, the console was left
running. This allowed a user to view the console even after the instance
was gone. Stop the console during unprovisioning to block this.

ConductorManager._set_console_mode will now bubble up any exceptions
raised, so that we can explode as needed during unprovisioning. This
does not have any side effects, as elsewhere it is run in it's own
thread and execution was complete after handling the exception.

Also change a few mock.ANY in the relevant unit tests to the actual task
object, as cleanup.
