Automatically download the latest stable release version of Kubernetes.
The ubuntu version of download-release.sh included in the binary release downloads the released .tar.gz file again. Right now the version of the downloaded file is manually encoded within the script. This change fetches the released version automatically, similar to the shell script available on the main Kubernetes site below:
https://get.k8s.io/
Ideally the installation on bare metal ubuntu should work with the files available in the already downloaded package.

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

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.
