Description of problem:
- When we run oc adm migrate storage, we got following error:

```
    "stdout": "E0507 17:21:02.645139 error:     -n xxx pods/config-rest-2-thzt8: pods \"config-rest-2-thzt8\" not found\nE0507 17:21:02.708902 error:     -n xxx pods/end-to-end-test-1-668xr: pods \"end-to-end-test-1-668xr\" not found\nE0507 17:21:02.741192 error:     -n xxx pods/kafka-1-zlc9b: pods \"kafka-1-zlc9b\" not found\nsummary: total=38931 errors=3 ignored=0 unchanged=28861 migrated=10067\ninfo: to rerun only failing resources, add --include=pods\nerror: 3 resources failed to migrate",
    "stdout_lines": [
        "E0507 17:21:02.645139 error:     -n xxx pods/config-rest-2-thzt8: pods \"config-rest-2-thzt8\" not found",
        "E0507 17:21:02.708902 error:     -n xxx pods/end-to-end-test-1-668xr: pods \"end-to-end-test-1-668xr\" not found",
        "E0507 17:21:02.741192 error:     -n xxx pods/kafka-1-zlc9b: pods \"kafka-1-zlc9b\" not found",
        "summary: total=38931 errors=3 ignored=0 unchanged=28861 migrated=10067",
        "info: to rerun only failing resources, add --include=pods",
        "error: 3 resources failed to migrate"
    ]
```

- Root cause of this issue is that "# oc adm --config=/etc/origin/master/admin.kubeconfig migrate storage --include=* --confirm" in "TASK [Upgrade all storage]" fails if pods are re-started(re-created).

Version-Release number of the following components:
- OCP 3.7

How reproducible: 10%

Steps to Reproduce:
1. Delete or re-create pods during oc adm migrate storage. (It happens usually by CrashLooping pods)

Actual results:
- Please refer to the error above.

Expected results:
- Success upgrade playbook without error.
- We would like to request to increase success rate of "oc adm migrate storage" (TASK [Upgrade all storage]), since upgrade playbook took long time and re-run the playbook is bothering.
