add index template for es aggregations
This index template helps us to do es aggregations of namespace_name, pod_name and container_name. Then after doing eggs, we will get the whole name not all the spilt pieces.
fix#25127
The guestbook-go example is broken because the latest tag of redis has
moved to redis 3.0 which speaks a new protocol. This means that the
slaves, which have fixed 2.0 versions, will error out on the protocol:
```
[7] 15 May 23:37:44.403 # Can't handle RDB format version 7
[7] 15 May 23:37:44.403 # Failed trying to load the MASTER synchronization DB from disk
[7] 15 May 23:37:45.333 * Connecting to MASTER redis-master:6379
[7] 15 May 23:37:45.427 * MASTER <-> SLAVE sync started
```
In this case the app simply never persists data.

Build hyperkube in hack/local-up-cluster instead of separate binaries
This speeds up the build time a lot.
Also add arm64 as a valid arch
This is quite trivial. Let's get it in asap

Use --format='value(name)' with gcloud instead of grep/awk/cut
Fixing our fragile parsing of `gcloud` is getting old (#24746, #25159, maybe others?).
Instead, let's just get the proper output out of `gcloud` in the first place.

Support struct,array,slice types when sorting kubectl output
Fixes https://github.com/kubernetes/kubernetes/issues/24328.
Briefly, `sorting_printer` only take cares of the following type kinds:
* `reflect.Int, reflect.Int8, reflect.Int16, reflect.Int32, reflect.Int64`
* `reflect.Uint, reflect.Uint8, reflect.Uint16, reflect.Uint32, reflect.Uint64`
* `reflect.Float32, reflect.Float64`
* `reflect.String`
* `reflect.Ptr`
This commit aims to add `reflect.Struct, reflect.Slice, reflect.Array`.

validate third party resources
addresses validation portion of https://github.com/kubernetes/kubernetes/issues/22768
* ThirdPartyResource: validates name (3 segment DNS subdomain) and version names (single segment DNS label)
* ThirdPartyResourceData: validates objectmeta (name is validated as a DNS label)
* removes ability to use GenerateName with thirdpartyresources (kind and api group should not be randomized, in my opinion)
test improvements:
* updates resttest to clean up after create tests (so the same valid object can be used)
* updates resttest to take a name generator (in case "foo1" isn't a valid name for the object under test)
action required for alpha thirdpartyresource users:
* existing thirdpartyresource objects that do not match these validation rules will need to be removed/updated (after removing thirdpartyresourcedata objects stored under the disallowed versions, kind, or group names)
* existing thirdpartyresourcedata objects that do not match the name validation rule will not be able to be updated, but can be removed

etcd_watcher: make Deleted Event.Object's version consistent
### What's the problem?
In [sendDelete()](995f022808/pkg/storage/etcd/etcd_watcher.go (L437-L442)), Deleted Event.Object's resource version will be set to the latest resource version. This is actually an assumption made by cacher that all later events should have objects with larger verions; See [here](995f022808/pkg/storage/cacher.go (L579-L581)).
In sendModify(), it could also return Deleted event. However, the resource version is still the old version, which is inconsistent behavior with sendDelete().
### What's this PR?
This PR sets the version of oldObj in sendModify() to be the latest version.
Provided unit test for it.

rkt: Refactor GarbageCollect to enforce GCPolicy.
Previously, we uses `rkt gc` to garbage collect dead pods, which is very coarse, and can cause the dead pods to be removed too aggressively.
This PR improves the garbage collection, now after one GC iteration:
- The deleted pods will be removed.
- If the number of containers exceeds gcPolicy.MaxContainers,
then containers whose ages are older than gcPolicy.minAge will be removed.

Rate limitting requeue
I think this will do what I want in almost every case. I'm going to try it out for a single writer quota evaluation.
`NewRateLimitingQueue(NewControllerRateLimiter(qps, burst))` gives an `AddRateLimited(item)` that backs off based on the max of a bucket and exponential backoff per item.
@liggitt Want to see if the interface works for you too?

Moving federation-apiserver to use genericapiserver.ServerRunOptions and deleting federation-apiserver options
The remaining params were related to authz and authn and one parameter for WatchCacheSize.
Have moved them to genericapiserver.ServerRunOptions and now federation-apiserver can just use genericapiserver.ServerRunOptions()

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.
