WIP - Handle map[]struct{} in DeepCopy
Deep copy was not properly handling the empty struct case we use for Sets.
@lavalamp I need your expertise when you have some time - the go2idl parser is turning sets.String into the following tree:
type: sets.String kind: Alias
underlying: map[string]sets.Empty kind: Map
key: string kind: Builtin
elem: set.Empty kind: Struct
^
should be Alias
Looking at tc.Named, I'm not sure what the expected outcome would be and why you flatten there.
While testing this fix in OpenShift it was discovered that the
PackageConstraint was overly aggressive - types that declare a public
copy function should always return true. PackageConstraint is intended
to limit packages where we might generate deep copy function, rather
than to prevent external packages from being consumed.
Downstream generators that want to reuse the upstream generated types
need to be able to define a different ignore tag (so that they can see
the already generated types).

Track object modifications in fake clientset
Fake clientset is used by unit tests extensively but it has some
shortcomings:
- no filtering on namespace and name: tests that want to test objects in
multiple namespaces end up getting all objects from this clientset,
as it doesn't perform any filtering based on name and namespace;
- updates and deletes don't modify the clientset state, so some tests
can get unexpected results if they modify/delete objects using the
clientset;
- it's possible to insert multiple objects with the same
kind/name/namespace, this leads to confusing behavior, as retrieval is
based on the insertion order, but anchors on the last added object as
long as no more objects are added.
This change changes core.ObjectRetriever implementation to track object
adds, updates and deletes.
Some unit tests were depending on the previous (and somewhat incorrect)
behavior. These are fixed in the following few commits.

TLS bootstrap API group (alpha)
This PR only covers the new types and related client/storage code- the vast majority of the line count is codegen. The implementation differs slightly from the current proposal document based on discussions in design thread (#20439). The controller logic and kubelet support mentioned in the proposal are forthcoming in separate requests.
I submit that #18762 ("Creating a new API group is really hard") is, if anything, understating it. I've tried to structure the commits to illustrate the process.

Specifying // +protobuf.nullable=true on a Go type that is an alias of a
map or slice will generate a synthetic protobuf message with the type
name that will serialize to the wire in a way that allows the difference
between empty and nil to be recorded.
For instance:
// +protobuf.nullable=true
types OptionalMap map[string]string
will create the following message:
message OptionalMap {
map<string, string> Items = 1
}
and generate marshallers that use the presence of OptionalMap to
determine whether the map is nil (rather than Items, which protobuf
provides no way to delineate between empty and nil).

Adding Services to federation clientset
Commits:
1. Regenerate the client without any changes to client-gen
2. Update clientgen to add a parameter to specify generating client only for Services v1 object.
3. Regenerate federation_internalclientset
4. Regenerate federation_release_1_3
Second commit is the most important one. Other 3 commits are auto generated by running client-gen.
I have added a command line argument to client-gen that takes in a list of group/version/resource. If a group version is part of this list, then only the resources in this list are included in the client. For other group versions, the existing check of genclient=true in types.go is used.
Other alternatives considered were:
* Update genclient in types.go to mention the clientset name in which it should be included instead of just saying genclient=true (so Services will say genclient=core,federation while all other v1 resources will say genclient=core). This requires a code change in types.go to change a client set.
* Create another types.go which will only include Services and use that to generate federation clientset. This will lead to duplicate Service definition.

pkg/apis/rbac: Add Openshift authorization API types
This PR updates #23396 by adding the Openshift RBAC types to a new API group.
Changes from Openshift:
* Omission of [ResourceGroups](4589987883/pkg/authorization/api/types.go (L32-L104)) as most of these were Openshift specific. Would like to add the concept back in for a later release of the API.
* Omission of IsPersonalSubjectAccessReview as its implementation relied on Openshift capability.
* Omission of SubjectAccessReview and ResourceAccessReview types. These are defined in `authorization.k8s.io`
~~API group is named `rbac.authorization.openshift.com` as we omitted the AccessReview stuff and that seemed to be the lest controversial based on conversations in #23396. Would be happy to change it if there's a dislike for the name.~~ Edit: API groups is named `rbac`, sorry misread the original thread.
As discussed in #18762, creating a new API group is kind difficult right now and the documentation is very out of date. Got a little help from @soltysh but I'm sure I'm missing some things. Also still need to add validation and a RESTStorage registry interface. Hence "WIP".
Any initial comments welcome.

client-gen: use serializer instead of codec for versioned client

Client-gen: Add fake clients to testoutput; fix the imports in fake clients
Start generating fake client in the testoutput, so that we can check the fake client is generated correctly under extreme conditions.

Client-gen: handle dotted group name, e.g., "authentication.k8s.io"
The client-gen used to assume the group name doesn't include dot, but it's not true, e.g., we have group `authentication.k8s.io`.
With this PR, Client-gen will use the full group name when creating directory (e.g., the client for the authentication group will be generated at pkg/client/clientset_generated/release_1_3/typed/`authentication.k8s.io`/v1/). However, because golang doesn't allow dot in variable/function names, so when the group name is used as part of variable/function name, client-gen extracts the part before the first dot (e.g., authentication).
This PR also changes the group name of the test group from `testgroup` to `testgroup.k8s.io` to verify if client-gen generates sane code.

Additional go vet fixes
Mostly:
- pass lock by value
- bad syntax for struct tag value
- example functions not formatted properly
In order to allow a Go type to have a different internal representation,
provide the comment `// +protobuf.as=MESSAGENAME` which substitutes the
current message's members with the named message's members. Used by the
unversioned.Time type to have the same fields as unversioned.Timestamp
and to have an alternate serialization.

Migrate to the new conversion generator - part1
This PR contains two commits:
- few more fixes to the generator
- migration of the pkg/api/v1 to use the new generator
The second commit is big, but I reviewed the changes and they contain:
- conversions between types that we didn't even generating conversion between
- changes in how we handle maps/pointers/slices - previously we were explicitly referencing fields, now we are using "shadowing in, out" to make the code more generic
- lack of auto-generated method for ReplicationControllerSpec (because these types are different (*int vs int for Replicas) and a preexisting conversion already exists
Most of issues in the first commit (e.g. adding references to "in" and "out" for slices/maps/points) were discovered by our tests. So I'm pretty confident that this change is correct now.
The protobuf tags contain the assigned tag id, which then ensures
subsequent generation is consistently tagging (tags don't change across
generations unless someone deletes the protobuf tag).
In addition, generate final proto IDL that is free of gogoproto
extensions for ease of generation into other languages.
Add a flag --keep-gogoproto which preserves the gogoproto extensions in
the final IDL.
Remove Codec from versionInterfaces in meta (RESTMapper is now agnostic
to codec and serialization). Register api/latest.Codecs as the codec
factory and use latest.Codecs.LegacyCodec(version) as an equvialent to
the previous codec.
