Implement resource details for PersistentVolumeClaims

[petar-cvit]

Is your feature request related to a problem? Please describe.
When fetching resources for a Module, some resources are supported to return details about a specific resource. For example, the endpoint for Deployments will return more information about pods and their statuses, and the endpoint for Services will return information about the ports.

If you want to fetch information about a Deployment form default namespace called demo-app you would call:
/resources?group=apps&version=v1&kind=Deployment&name=demo-app&namespace=default

The goal of the issue is to support PersistentVolumeClaims on the same endpoint. The endpoint for fetching PVC data would look like this: /resources?group=&version=v1&kind=PersistentVolumeClaim&name=<name>&namespace=<namespace>.

The handler function for the endpoint is here, and you will have to handle a new type here.

In the response, you can add the size of the PVC, access mode, and anything else you would find useful.
