Consolidate duplicate CRDs

[yaker-gh]

CRDs are duplicated between helm-charts/crds/ and terraform/manifests/. Every sync from pulp-operator requires updating both, and they can drift.

The terraform copies don't use template variables - they're static YAML. We could have terraform read directly from helm-charts/crds/ instead:

locals {
  manifests = fileset(path.module, "manifests/*.yaml")
  crds      = fileset("${path.module}/../helm-charts/crds", "*.yaml")
}

resource "kubernetes_manifest" "crds" {
  for_each = local.crds
  manifest = yamldecode(file("${path.module}/../helm-charts/crds/${each.value}"))
}

resource "kubernetes_manifest" "roles" {
  for_each   = local.manifests
  manifest   = yamldecode(templatefile("${each.value}", { ... }))
  depends_on = [kubernetes_manifest.crds]
}

Then delete the CRDs from terraform/manifests/.
