Move /resetMetrics to DELETE /metrics
Reduces the surface area of the API server slightly and allows
downstream components to have deleteable metrics. After this change
genericapiserver will *not* have metrics unless the caller defines it
(allows different apiserver implementations to make that choice on their
own).

Add watch.Until, a conditional watch mechanism
A more powerful tool than wait.Poll, allows a watch interface to drive conditionals to react to changes on a resource or resources. Provide a set of standard conditions that are in common use in the code, and updates e2e to use a few of these.

phase 2 of cassandra example overhaul
Here's the next iteration in overhauling this example, towards https://github.com/kubernetes/kubernetes/issues/20961. This removes the pod adoption part, but doesn't (yet) otherwise change any of the resources used.
It also includes some README cleanup, and removes some explicit specification of labels in the rc yaml.
This PR doesn't yet add any commentary on how we're using the seed provider (re: https://github.com/kubernetes/kubernetes/issues/20961#issuecomment-190405959 etc.). Maybe we should add that.
Also: LMK if this PR should include any changes to the links out to the docs.

Add generalized performance data type in e2e test
For kubernetes/contrib/issues/564 and #15554.
This PR added two files in e2e test:
1) `perftype/perftype.go`: This file contains generalized performance data type. The type can be pretty printed in Json format and analyzed by other performance analyzing tools, such as [Perfdash](https://github.com/kubernetes/contrib/tree/master/perfdash).
2) `perf_util.go`: This file contains functions which convert e2e performance test result into new performance data type.
The new performance data type is now used in *Density test, Load test and Kubelet resource tracking*. It's easy to support other e2e performance test by adding new convert function in `perf_util.go`.

Clientset release 1.3
This PR creates the release 1.3 client set. We'll keep updating this client set until we cut release 1.3. In the meantime, the release 1.2 client set will be locked.
@lavalamp
This commit switch most functions in kubelet_stats.go to use the new API.
However, the functions that perform one-time resource usage retrieval remain
unchanged to be compatible with reource_usage_gatherer.go. They should be
handled separately.
Also, the new summary API does not provide the RSS memory yet, so all memory
checking tests will *always* pass. We plan to add this metrics in the API and
restore the functionality of the test.

Additional go vet fixes
Mostly:
- pass lock by value
- bad syntax for struct tag value
- example functions not formatted properly

Ensure object returned by volume getCloudProvider incorporates cloud config
This PR addresses https://github.com/kubernetes/kubernetes/issues/23517.
**Problem**
The existing GCE PD and AWS EBS volume plugin code were fetching cloud provider without specifying a cloud config: `cloudprovider.GetCloudProvider("gce", nil)`
This caused the cloud provider to use default auth mechanism, which is not acceptable for the provisioning controller running on GKE master.
**Fix**
This PR does the following:
* Modifies the GCE PD and AWS EBS volume plugin code to use the cloud provider object pre-constructed by the binary with a cloud config.
* Enable provisioning E2E test for GKE (to catch future issues).
Thanks to @cjcullen for debugging and finding the root cause! 👍
This should be cherry-picked into the v1.2 branch for the next release.

Update port forward e2e for go 1.6
Only close the stdout/stderr pipes from kubectl port-forward when we're truly done with the command,
instead of as soon as runPortForward exits.
Also try to gracefully stop kubectl port-forward via SIGINT, instead of always sending SIGKILL, as
this will help avoid spdy goroutine leaks in the Kubelet.
