fix(k8s): reconcile serviceMaps when using mesh namespace annotation

[lahabana]

Summary

We were not looking at annotations on the namespace when looking
at config map that need to be reconciled when service changes.

This would cause issue if pods were not individually annotated.

Testing

• Unit tests
• E2E tests
• Manual testing on Universal
• Manual testing on Kubernetes

Backwards compatibility

• [ ] Update UPGRADE.md with any steps users will need to take when upgrading.
• [ ] Add backport-to-stable label if the code follows our backporting policy

I don't think we need to look into a namespace.
Pod with kuma sidecar always has an annotation kuma.io/mesh: default. Example

apiVersion: v1
kind: Pod
metadata:
  annotations:
    kuma.io/builtindns: enabled
    kuma.io/builtindnsport: "15053"
    kuma.io/envoy-admin-port: "9901"
    kuma.io/mesh: default
    kuma.io/sidecar-injected: "true"
    kuma.io/sidecar-uid: "5678"
    kuma.io/transparent-proxying: enabled
    kuma.io/transparent-proxying-inbound-port: "15006"
    kuma.io/transparent-proxying-inbound-v6-port: "15010"
    kuma.io/transparent-proxying-outbound-port: "15001"
    kuma.io/virtual-probes: enabled
    kuma.io/virtual-probes-port: "9000"
