[Feature] add field `mcpserver.spec.deployment.labels` and `mcpserver.spec.deployment.annotations`

[Colvin-Y]

What would you like to be added:

• add field mcpserver.spec.deployment.labels and mcpserver.spec.deployment.annotations

Why is this needed:

• In production env, user may use svc mesh structure. In such case, may inject sidecar-container for mcp-server pod. The sidecar container config can from downward API which must be configured in pod annotations and labels.

Implemention:

• transport user define labels and annotations to mcp-server deployment.

If it's helpful, plz assign to me, I'm willing to contribute!

Hi, I'd like to work on this. I'll add the labels and annotations
fields to MCPServerDeployment spec and wire them through to the
generated Deployment pod template. Will have a PR shortly.

Hi, while investigating this issue I found that labels and annotations
fields are already implemented in the MCPServerDeployment spec and wired
through to the pod template. However, the production security sample
mcpserver-production-security.yaml had incorrect field formats for env
and secretRefs that would confuse users.

I've opened PR #133 to fix the sample. The labels and annotations
fields are already available and working as described in the issue.
