Subject: [PATCH] Add blanket "NoSchedule" toleration to trace pod

We have a few nodes that we couldn't `kubectl trace` effectively because they were tainted to prevent arbitrary pods from being scheduled to them.

In this case, however, we are specifically requesting for a pod to be scheduled to that node, but the taint was leaving the pod hanging in `Pending` until we manually edited the trace pod to add this toleration.
