feat: read resourcequotas from support-bundle

[banjoh]

  List resourcequotas:
  $ kubectl get resourcequotas -n default
  NAME            REQUEST                                                                 LIMIT                                    AGE
  compute-quota   pods: 1/20, requests.cpu: 0/4, requests.memory: 0/8Gi, services: 1/10   limits.cpu: 0/8, limits.memory: 0/16Gi   71m

  Get single resourcequota:
  $ kubectl get resourcequota compute-quota -n default
  NAME            REQUEST                                                                 LIMIT                                    AGE
  compute-quota   pods: 1/20, requests.cpu: 0/4, requests.memory: 0/8Gi, services: 1/10   limits.cpu: 0/8, limits.memory: 0/16Gi   71m
