oc logout fails to invalidate the token even if the request deletes oauthaccesstoken tokenname

Version-Release number of selected component (if applicable):
4.7.0-0.nightly-2020-12-17-201522

How reproducible:
Always

Steps to Reproduce:
1. oc delete clusterrolebinding.rbac system:oauth-token-deleters

2. oc login -u testuser-21 -p <password> https://api.test... --insecure-skip-tls-verify=true

$ oc whoami -t
sha256~zsYWkdwWK6bccxqKuCLXB4Mfy4eROhWFVz........

3. check oauthaccesstoken:
$ oc get oauthaccesstoken --context admin 
sha256~5sQAv5aegDPsV2vC2Ghc9KOSQhkggu1sImMtSlD....   testuser-21   openshift-challenging-client   2020-12-18T12:54:10Z   2020-12-19 12:54:10 +0000 UTC   https://oauth-openshift.apps.../oauth/token/implicit   user:full

4.$ oc logout --v 6

I1218 18:25:02.086436  213237 logout.go:143] Removed token from your local configuration.
Logged "testuser-21" out on "https://api.test...."


Actual results:

1] Able to login with the same token.

$ oc whoami --token=sha256~zsYWkdwWK6bccxqKuCLXB4Mfy4eROhWFVzI........
testuser-21

$ oc login --token=sha256~zsYWkdwWK6bccxqKuCLXB4Mfy4eROhWFVzI........
Logged into "https://api.test.qe.devcluster.openshift.com:6443" as "testuser-21" using the token provided.


Expected results:

Should delete successfully. After `oc logout`, `oc whoami --token "sha256~zsYWkdwWK6bccxqKuCLXB4Mfy4eROhWFVzI........"` should show "error: You must be logged in to the server (Unauthorized)"

Additional info:

In the logout (no matter oc or console or any other) should use useroauthaccesstoken instead of oauthaccesstoken due to the clusterrolebinding is deprecated and will be removed soon in next 4.8 version
