Easy PVC inspection plugin

[leomichalski]

Is your feature request related to a problem? Please describe.
Too much hassle to inspect volume contents.

Describe the solution you'd like
I just wrote a plugin to inspect the folders inside a PVC. Should I open a PR to the plugins folder?

Describe alternatives you've considered
I thought about integrating it in k9s, but I'm not sure if there's a docker image that everyone would consider safe to use. Any thoughts on this?

Additional context
Here's the plugin:

plugins:
  inspect-pvc:
    shortCut: s
    confirm: false
    description: Explore PVC
    scopes:
    - persistentvolumeclaims
    command: sh
    background: false
    args:
      - -c
      - |
        kubectl run --rm -it k9s-inspecting-${NAMESPACE}-${NAME} --image=busybox --restart=Never --namespace ${NAMESPACE} --context ${CONTEXT} --overrides='{
            "spec": {
                "containers": [
                    {

                        "name": "k9s-inspecting-${NAMESPACE}-${NAME}",
                        "volumeMounts": [
                            {

                                "name": "k9s-inspected-pvc"
                            }
                        ],

                    }
                ],
                "volumes": [
                    {

                        }
                    }
                ]
            }
        }' --command -- sh
