Rackspace improvements (OpenStack Cinder)
This adds PV support via Cinder on Rackspace clusters. Rackspace Cloud Block Storage is pretty much vanilla OpenStack Cinder, so there is no need for a separate Volume Plugin. Instead I refactored the Cinder/OpenStack interaction a bit (by introducing a CinderProvider Interface and moving the device path detection logic to the OpenStack part).
Right now this is limited to `AttachDisk` and `DetachDisk`. Creation and deletion of Block Storage is not in scope of this PR.
Also the `ExternalID` and `InstanceID` cloud provider methods have been implemented for Rackspace.

First pass at a GKE large cluster Jenkins job
Runs a 1000 node GKE parallel e2e test. On demand only. We'll add more
tests as I see what actually works - this is going to have some
flakiness on its own.

Add mpio support for iscsi
This allows the iscsi volume to check if a iscsi device belongs to a mpio device
If it does belong to the device then we make sure we mount the mpio device instead of
the raw device.
The code is based on the current FibreChannel volume support for mpio
example
/dev/disk/by-path/iqn-example.com.2999 -> /dev/sde
Then we check
/sys/block/[dm-X]/slaves/xx
until we find the [dm-X] containing /dev/sde and mount it
Additional work that can be done in future
1. Add multiple portal support to iscsi
2. Move the FibreChannel volume provider to use the code that has been extracted

Disable heapster job which has been broken for a month
https://github.com/kubernetes/kubernetes/issues/23538
This job is no longer producing a useful signal. http://kubekins.dls.corp.google.com/ shows that the last pass was nearly two months ago. I would like to disable the job until someone has the chance to fix it so we are not wasting jenkins resources, contributing to system instability.

Make fake client actions use fully qualified resource
The output of a versioned clientset is version object. The fake client used to assume only internal objects will be returned. This PR removes this assumption by making fake actions initialized with a fully qualified resource instead of a resource string.
We have to regenerate fake clients in release_1_2 clientset to let it compile. For the test fakes, we are breaking the backwards compatibility promise.
Part of #24155.

make storage enablement, serialization, and location orthogonal
This allows a caller (command-line, config, code) to specify multiple separate pieces of config information regarding storage and have them properly composed at runtime. The information provided is exposed through interfaces to allow alternate implementations, which allows us to change the expression of the config moving forward. I also fixed up the types to be correct as I moved through.
The same options still exist, but they're composed slightly differently
1. specify target etcd servers per Group or per GroupResource
1. specify storage GroupVersions per Groups or per GroupResource
1. specify etcd prefixes per GroupVersion or per GroupResource
1. specify that multiple GroupResources share the same location in etcd
1. enable GroupResources by GroupVersion or by GroupResource whitelist or GroupResource blacklist
The `storage.Interface` is built per GroupResource by:
1. find the set of possible storage GroupResource based on the priority list of cohabitators
1. choose a GroupResource from the set by looking at which Groups have the resource enabled
1. find the target etcd server, etcd prefix, and storage encoding based on the GroupResource
The API server can have its resources separately enabled, but for now I've kept them linked.
@liggitt I think we need this (or something like it) to be able to go from config to these interfaces. Given another round of refactoring, we may be able to reshape these to be more forward driving.
@smarterclayton this is important for rebasing and for a seamless 1.2 to 1.3 migration for us.

Increase provisioning test timeouts.
We've encountered flakes in our e2e infrastructure when kubelet took more than one minute to detach a volume used by a deleted pod.
Let's increase the wait period from 1 to 3 minutes. This slows down the test by 2 minutes, but it makes the test more stable.
In addition, when kubelet cannot detach a volume for 3 minutes, let the test wait for additional recycle controller retry interval (10 minutes) and hope the volume is deleted by then. This should not increase usual test time, it makes the test stable when kubelet is _extremely_ slow when releasing the volume.

etcd3 store: provide compactor util
What's this PR?
- Provides a util to compact keys in etcd.
Reason:
We want to save the most recent 10 minutes event history. It should be more than enough for slow watchers. It is not number based, so it can tolerate event bursts too. We do not want to save longer since the current storage API cannot take advantage of the multi-version key yet. We might keep a longer history in the future.

Remove requirement that Endpoints IPs be IPv4
Signed-off-by: André Martins <aanm90@gmail.com>
Release Note: The `Endpoints` API object now allows IPv6 addresses to be stored. Other components of the system are not ready for IPv6 yet, and many cloud providers are not IPv6 compatible, but installations that use their own controller logic can now store v6 endpoints.

Apigroup and alpha resource for petset
I'm still writing unittests, validation and comments but I'm planning to punt on anything more involved since this is alpha.

hack: change update-swagger-spec.sh apiserver defaults
Removing the explicit list of KUBE_API_VERSIONS will cause the apiserver
to enable all APIs by default. This change reduces the amount of script
hacking needed to add new API groups in the future.
