Some e2e tests use wget to check connectivity, and the default e2e
timeout is 900s. This change allows the timeout to be specified on a
check-by-check basis. This will also make the check useful for negative
checks (like those used by openshift to validate isolation) since a
short timeout is suggested where connectivity is not expected.

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.

This allows others to leverage the existing E2E code to test some
patched kube binary by simply overriding the bucket and reusing many of
the existing scripts
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.
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.

Honor starting resourceVersion in watch cache
Compare the requested resourceVersion to each event's resourceVersion to ensure events that occurred
in the past are not sent to the client.

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.

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.
