Bug 1942938

These improvements are significantly helping debugging clusters so I'm bumping priority for those to high.

1) [root@localhost oc]# ./oc version 
Client Version: 4.7.99
Server Version: 4.5.37
Kubernetes Version: v1.18.3+cdb0358
[root@localhost oc]# ./oc adm must-gather 
[must-gather      ] OUT Using must-gather plug-in image: quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:0e29a7270bff4c9ca267b5a1976d2e4db2a1e86146aca6fc7145cba5b3fc09d8

We could see the summary to oc must-gather. 



2) From the output of must-gather for pods :
[root@localhost openshift-etcd]# tree pods/
pods/
├── etcd-ip-10-0-169-230.us-west-1.compute.internal
│   ├── etcd
│   │   └── etcd
│   │       └── logs
│   │           ├── current.log
│   │           ├── previous.insecure.log
│   │           └── previous.log
│   ├── etcdctl
│   │   └── etcdctl
│   │       └── logs
│   │           ├── current.log
│   │           ├── previous.insecure.log
│   │           └── previous.log
│   ├── etcd-ensure-env-vars
│   │   └── etcd-ensure-env-vars
│   │       └── logs
│   │           ├── current.log
│   │           ├── previous.insecure.log
│   │           └── previous.log


we could make sure the function for : stop trying to gather metrics and other endpoints directly from pods, has works well . 


3)  Check the function for : indicate how many bytes the hidden secret key was:

[root@localhost ~]# ./oc get secret my-secret -o yaml 
apiVersion: v1
data:
  key1: c3VwZXJzZWNyZXQ=
  key2: dG9wc2VjcmV0
kind: Secret


[root@localhost secrets]# more my-secret.yaml 
---
apiVersion: v1
data:
  key1: MTEgYnl0ZXMgbG9uZw==
  key2: OSBieXRlcyBsb25n
kind: Secret

So this function works well . 

4) Check the function for :inspect clusteroperators as a backup to must-gather if it fails

 [root@localhost oc]# ./oc adm  must-gather --image='quay.io/openshift-release-dev/ocp-v4.0-art-dev:nonexist' 
[must-gather      ] OUT Using must-gather plug-in image: quay.io/openshift-release-dev/ocp-v4.0-art-dev:nonexist

we could see when the must-gather failed , will start the inspect command .
