45a436ac24 Merge pull request #36909 from sttts/sttts-discovery-with-verbs
Automatic merge from submit-queue (batch tested with PRs 37370, 37003, 36909)

Add verbs to APIResourceInfo for discovery

Verbs will be used by generic controllers (gc, namespace) to avoid unnecessary API calls, reducing load on the apiserver. E.g. not all objects can be deleted.

Example:
```json
{
  "kind": "APIResourceList",
  "apiVersion": "v1",
  "groupVersion": "batch/v1",
  "resources": [
    {
      "name": "jobs",
      "namespaced": true,
      "kind": "Job",
      "verbs": [
        "create",
        "delete",
        "deletecollection",
        "get",
        "list",
        "update",
        "watch"
      ]
    },
    {
      "name": "jobs/status",
      "namespaced": true,
      "kind": "Job",
      "verbs": [
        "create",
        "get"
      ]
    }
  ]
}

cd560926bd Merge pull request #36889 from wojtek-t/reuse_fields_and_labels
Automatic merge from submit-queue

Reuse fields and labels

This should significantly reduce memory allocations in apiserver in large cluster.
Explanation:
- every kubelet is refreshing watch every 5-10 minutes (this generally is not causing relist - it just renews watch)
- that means, in 5000-node cluster, we are issuing ~10 watches per second
- since we don't have "watch heartbets", the watch is issued from previously received resourceVersion
- to make some assumption, let's assume pods are evenly spread across pods, and writes for them are evenly spread - that means, that a given kubelet is interested in 1 per 5000 pod changes
- with that assumption, each watch, has to process 2500 (on average) previous watch events
- for each of such even, we are currently computing fields.

This PR is fixing this problem.

move parts of the mega generic run struct out

This splits the main `ServerRunOptions` into composeable pieces that are bindable separately and adds easy paths for composing servers to run delegating authentication and authorization.

@sttts @ncdc alright, I think this is as far as I need to go to make the composing servers reasonable to write.  I'll try leaving it here

Revision handling in federated deployment controller

Stop deleting underlying services when federation service is deleted

Fixes https://github.com/kubernetes/kubernetes/issues/36799

Fixing federation service controller to not delete services from underlying clusters when federated service is deleted.
None of the federation controller should do this unless explicitly asked by the user using DeleteOptions. This is the only federation controller that does that.

Automatic merge from submit-queue

Fixing the logic to select first cluster in federated ingress controller

Ref https://github.com/kubernetes/kubernetes/issues/36074.

Before this change, ingress controller was using cluster with clusterIndex = 0 as the first cluster to create the ingress in.
But the ordering of clusters can change and hence ingress controller ended up creating the ingress in multiple clusters.
This PR fixes it by using an annotation on federated ingress. Controller now picks up a cluster randomly as the first cluster and creates ingress there. This clusters name is stored as an annotation on the federated ingress. Contoller does not create an ingress in any other cluster if this annotation is set on the federated ingress and IP has not been propagated. Once IP has been propagated, controller creates the ingress in all clusters.

67dc87395b Merge pull request #36869 from madhusudancs/kubefed-join-context-secret-name-flags
Automatic merge from submit-queue

[Federation][join-flags] Add flags for cluster context and secret names while joining clusters to federation.

Vast majority of cluster contexts are not RFC 1123 subdomains. Since
cluster and secret names for the API objects are derived from the
cluster context name, there is no way for users to join clusters
with such context names to federation, unless they modify the context
name in their kubeconfigs itself. That's a lot of inconvenience and
entirely goes against the goal and beats the purpose of the `kubefed`
tool. So we are providing these flags to allow users to override these
values.

Also, since users register their clusters with federation, it is makes
sense in terms of user experience to make the cluster name a positional
argument because that feels more natural. Also, specifying cluster name
in the join command as a mandatory positional argument make
`kubefed join` consistent with `kubefed unjoin`. This also means
`--cluster-context` is now made a flag and defaults to cluster name if
unspecified.

`--secret-name` also defaults to the cluster name if unspecified.

Fields with omitempty tag should still be considered as optional

We've added an "+optional" tag while ago for optional fields. Before that OpenAPI spec generated assumed all fields with "omitempty" in their json tags are optional. This should be still the case (as well as +optional tag) until these two things happen:

- We update all documentation asking developers to use +optional (My bad, I should have added this after the +optional PR)
- We fix swagger 1.2 spec generator to use +optional instead of omitempty.

Make desired objects in fed controller reconcilation function fully writable

When creating desired objects for sub-cluster in reconciliate functions we don't make full copies. This may result in unexpected race condition in the future when someone actually adds some object modifications (not needed in most cases but anyway - the cost of extra copy will be relatively small comparing to inter-cluster traffic). In case of ReplicaSet and Deployment the spec copy was a shallow one - ok for setting just replicas but also error-prone in the future.
