This PR changes behavior of the scheduler such that a task group with a deployment that is failed or paused will not cause the scheduler to skip migrations. The reason for this change is that it causes a bad UX when draining nodes with allocations that are part of a failed/paused deployment. These operations should not be coupled in any way and this remedies that. Prior behavior was still correct, but required either jobs to transistion to a healthy state or for the node to hit its drain deadline.
