Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

```release-note
The main repository does not keep multiple releases of clientsets anymore. Please find previous releases at https://github.com/kubernetes/client-go

Enable OpenAPI spec validation
Spec validation was failing on Jenkins. I am enabling it in this PR to figure out if we can get it pass. No review is necessary until all test passes.
Mark NodeLegacyHostIP will be deprecated in 1.7;
Let cloudprovider that used to only set NodeLegacyHostIP set the IP as both InternalIP and ExternalIP, to allow dprecation in 1.7

Remove static kubelet client, refactor ConnectionInfoGetter
Follow up to https://github.com/kubernetes/kubernetes/pull/33718
* Collapses the multi-valued return to a `ConnectionInfo` struct
* Removes the "raw" connection info method and interface, since it was only used in a single non-test location (by the "real" connection info method)
* Disentangles the node REST object from being a ConnectionInfoProvider itself by extracting an implementation of ConnectionInfoProvider that takes a node (using a provided NodeGetter) and determines ConnectionInfo
* Plumbs the KubeletClientConfig to the point where we construct the helper object that combines the config and the node lookup. I anticipate adding a preference order for choosing an address type in https://github.com/kubernetes/kubernetes/pull/34259

convert TPR controller to posthook instead of disable flag
Converts the third party resource controller into a posthook using a loopback client instead going direct to etcd. This let's us eliminate more flags and special-casing during initialization. Also, using a client brings us closer to building this without side-effects for downstream composers.

Change legacy API resource registration
Updates the legacy API resource registration to emphasize its different-ness and to simplify supporting objects. The option has to remain in the genericapiserverconfig for multiple prefixes to enable cases where composers/extenders had composed additional groupless APIs. See OpenShift as an example.
However this is now transparent to "normal" composers.
@ncdc since sttts is out.

remove testapi.Default.GroupVersion
I'm going to try to take this as a series of mechanicals. This removes `testapi.Default.GroupVersion()` and replaces it with `registered.GroupOrDie(api.GroupName).GroupVersion`.
@caesarxuchao I'm trying to see how much of `pkg/api/testapi` I can remove.

Cleanup non-rest apiserver handlers
- rename MuxHelper -> PathRecorderMux
- move non-rest handlers into routes packages within genericapiserver and `pkg/routes` (those from master)
- move ui and logs handlers out of genericapiserver (they are
not generic)
- make version handler configurable (`config.EnableVersion`)

restrict discoverable versions to those that have resources
Prevents versions with no resources from appearing in discovery.
@soltysh ptal. I think you have some issues for this, mind wiring them up?
