TaskRun pod get evicted during a Graceful Termination event, such as a node drain

      A TaskRun should not be evicted during a node drain until the status of the TaskRun is either `Completed` or `Failed`.

      Evicting a TaskRun in the middle of its execution can lead to unforeseen and harmful situations.

       

      How to reproduce:

      // create the TaskRun
$ cat << EOF | oc create -f -
apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: sleeping-reproducer
spec:
  taskSpec:
    steps:
    - name: sleep
      image: registry.access.redhat.com/ubi8/ubi
      script: |
        echo "sleeping 300s ..." && sleep 300
EOF

// drain the node where the TaskRun is running
$ oc adm drain $(oc get po -l tekton.dev/taskRun=sleeping-reproducer -o jsonpath='{.items[0].spec.nodeName}') --delete-emptydir-data --ignore-daemonsets

      Doing so will cause the eviction of the Pod/TaskRun sleeping-reproducer.
