kubernetes_deployment does not support namespace_selector for pod_anti_affinity

[matpen]

Description

It looks like neither kubernetes_deployment nor kubernetes_deployment_v1 support the namespace_selector field for pod_anti_affinity (and possibly for pod_affinity). This is unfortunate, because it is the only way to specify a match in "all namespaces" (by passing an empty selector).

Potential Terraform Configuration

resource "kubernetes_deployment" "my_app" {
  ...
  spec {
    ...
    template {
      ...
      spec {
        ...
        affinity {
          pod_anti_affinity {
            required_during_scheduling_ignored_during_execution {
              label_selector {
                match_expressions {
                  key = "app"
                  operator = "In"
                  values = ["my-app"]
                }
              }
              namespace_selector = {} # TODO this does not work
              topology_key = "kubernetes.io/hostname"
            }
          }
        }
        ...

@alexsomesan, I can see other resources already have support for namespace_selector, are you be open to a PR for this enhancement?

I can confirm that also in pod_affinity the block namespace_selector isn't recognized.

The block namespace_selector isn't recognized also under deployment.spec.template.spec.affinity.pod_affinity.preferred_during_scheduling_ignored_during_execution.pod_affinity_term.
