Client-gen: handle dotted group name, e.g., "authentication.k8s.io"
The client-gen used to assume the group name doesn't include dot, but it's not true, e.g., we have group `authentication.k8s.io`.
With this PR, Client-gen will use the full group name when creating directory (e.g., the client for the authentication group will be generated at pkg/client/clientset_generated/release_1_3/typed/`authentication.k8s.io`/v1/). However, because golang doesn't allow dot in variable/function names, so when the group name is used as part of variable/function name, client-gen extracts the part before the first dot (e.g., authentication).
This PR also changes the group name of the test group from `testgroup` to `testgroup.k8s.io` to verify if client-gen generates sane code.

Fix GKE kube-up to correctly find an IGM from a multi-zone cluster
I've confirmed that this successfully brings up a cluster, fixing the immediate issue with the new e2e test. Sorry about not properly vetting it in the original PR (#24075).
This does cause a warning message to be printed based on the handling of the NUM_NODES variable though, which I could fix if you guys think it's worth it:
```
Detected 6 ready nodes, found 6 nodes out of expected 3. Found more nodes than expected, your cluster may not behave correctly.
```

add a delayed queueing option to the workqueue
Adds delayed requeuing to the workqueue so that I requeue an item to be retried at some later time in my controller with a series of backoff rules. It lets me have the best of the retryManager and the work queue de-duping. Tracking failures and backoffs is on the caller
@smarterclayton @pweil- this would help us move to using the informer everywhere and de-duping at that level.

Make kubectl bash-completion namespace and resource alias aware
- filter resource listing by `--namespace` flag given before in the command line
```bash
$ kubectl get pod --namespace=kube-system <tab><tab>
kube-dns-v9-2wuzj kube-dns-v9-llqxa
```
- add completion of `--namespace`
```bash
$ kubectl get pod --namespace=<tab><tab>
[*] default ingress kube-system
```
- add support for plural nouns and aliases like `rc`

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`.

Use OomScoreAdj in kubelet for newer docker api
fixes: #20121
Related: client side PR [pull 454](https://github.com/fsouza/go-dockerclient/pull/454)
Godeps has already been updated to `0099401a7342ad77e71ca9f9a57c5e72fb80f6b2`, which included client side's modification. But it seems too aggressive to upgrade the docker api version of kubelet.

Unit test for negative value of allocatable resources
Introduce unit test for checking resource quantities for kubelet's allocatable resources.
Covered values:
* negative quantity value: error expected
* invalid quantity unit: error expected
* valid quantity: error not expected
Running go test with -v, returned error are logged as well for more information:
```shell
=== RUN TestValueOfAllocatableResources
--- PASS: TestValueOfAllocatableResources (0.00s)
server_test.go:47: Returned err: "resource quantity for \"memory\" cannot be negative: -150G"
server_test.go:47: Returned err: "unable to parse quantity's suffix"
PASS

Don't remove kubemark binaries

Trusty: Fixes for running GKE master
This PR includes two fixes for running GKE master on our image:
(1) The kubelet command line assembly had a missing part for cbr0. We did not catch it because the code path is not covered by OSS k8s tests;
(2) Remove the "" from the variables in the cert files. It causes a parsing issue in GKE. Again, this code path is not covered by k8s tests.
This PR also refactors the code for assembling kubelet flag. I move all logic into a single function assemble_kubelet_flags in configure-helper.sh for better readability and also simplify node.yaml and master.yaml.
@roberthbailey @dchen1107 please review it, and mark it as cherrypick-candidate. This PR is verified by @maisem. Together with his CL for GKE, we can run GKE cluster with master on our image and nodes on ContainerVM.

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.
