Description of problem:

If the VM was live migrated, there will be virt-launcher pods with the status "completed".

~~~

1. oc get pod
   NAME READY STATUS RESTARTS AGE
   virt-launcher-rhel8-i181f1yxkfqqrv83-75lxb 1/1 Running 0 55s
   virt-launcher-rhel8-i181f1yxkfqqrv83-bn728 0/1 Completed 0 86s
   virt-launcher-rhel8-i181f1yxkfqqrv83-lmlqv 0/1 Completed 0 29h

   virt-launcher-rhel8-i181f1yxkfqqrv83-v5lvb 0/1 Completed 0 73s
   ~~~

must-gather is trying to do `oc exec` on all these completed pods which will fail. This will result in multiple empty files in must gather.

Version-Release number of selected component (if applicable):

OpenShift Virtualization 4.13.1

How reproducible:

100%

Steps to Reproduce:

1. Migrate VMs multiple times so that we will have virt-launcher pods with "completed" status.

2. Collect a must-gather and list the files under namespace/<namespace-name>/vms/<vm-name>

There will be multiple empty files under it.

Actual results:

must-gather: Multiple empty files under vms/<vm-name> if the VM was live migrated.

Expected results:

it should only do `oc exec` on running virt-launcher pods.
