remove duplicate errors from aggregate error outputs
release-label-none
Duplicate error messages are sometimes shown when displaying aggregate errors:
`$ kubectl label pod/database-1-fn0r7 qwer1345%$$#=self`
```
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')

This patch removes any duplicate messages (adjacent or not) that appear in the final list of errors.

Possible resource types include (case insensitive): pods (po), services (svc), deployments,
replicasets (rs), replicationcontrollers (rc), nodes (no), events (ev), limitranges (limits),
persistentvolumes (pv), persistentvolumeclaims (pvc), resourcequotas (quota), namespaces (ns),
serviceaccounts (sa), ingresses (ing), horizontalpodautoscalers (hpa), daemonsets (ds), configmaps,
componentstatuses (cs), endpoints (ep), and secrets.
By specifying the output as 'template' and providing a Go template as the value
of the --template flag, you can filter the attributes of the fetched resource(s).

kubectl.PossibleResourceTypes missing some resouces such as jobs quota.
describe and explain have the same problem.
i think using valid_resources to replace kubectl.PossibleResourceTypes more suitable.

add --raw for kubectl get
Adds a `--raw` option to `kubectl get` that allow you specify your URI, but use the transport built by `kubectl`. This is especially useful when working with secured environments that require authentication and authorization to hit non-api endpoints. For example, `kubect get --raw /metrics` or if you want to debug a watch with a view at the exact data `kubectl get --raw '/api/v1/namespaces/one/replicationcontrollers?watch=true'`.

componentstatuses (aka 'cs), endpoints (aka 'ep'), petsets (alpha feature, may be unstable) and secrets.
This command will hide resources that have completed. For instance, pods that are in the Succeeded or Failed phases.
You can see the full results for any resource by providing the '--show-all' flag.
By specifying the output as 'template' and providing a Go template as the value
of the --template flag, you can filter the attributes of the fetched resource(s).
