Enhance MCPServer with emptyDir

[aliok]

Fixes #43

Looks like this:

apiVersion: mcp.x-k8s.io/v1alpha1
kind: MCPServer
metadata:
  name: mcpserver-with-emptydir
  namespace: default
spec:
  config:
    storage:
      # EmptyDir for cache with larger size limit
      - path: /tmp/cache
        permissions: ReadWrite
        source:
          type: EmptyDir
          emptyDir:
            sizeLimit: 500Mi

I have my own E2E test suite and existing MCP servers worked fine with this branch of the operator: https://github.com/mcp-kube/mcp-lifecycle-operator-e2e-tests/actions/runs/23618657354/job/68792484134#step:10:43

Hi @aliok. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Damn, I was creating this PR when creating the prev one with the same issue, forgot to update it.
Thanks for catching it!
