Make "attach" and "exec" rejection in proxy more explicit
```release-note
kubectl proxy changed to now allow urls to pods with "attach" or "exec" in the pod name
```
The more explicit regular expression for rejection makes a possibility of accessing pods (or any other resources) which contain "attach" or "exec" in their names via proxy API. It was not possible before.
Also, the reference for "run" resource was removed, because it doesn't exist in any of k8s APIs currently.

AWS: Added experimental option to skip zone check
This pull request resolves#28380. In the vast majority of cases, it is appropriate to validate the AWS region against a known set of regions. However, there is the edge case where this is undesirable as Kubernetes may be deployed in an AWS-like environment where the region is not one of the known regions.
By adding the optional **DisableStrictZoneCheck true** to the **[Global]** section in the aws.conf file (e.g. /etc/aws/aws.conf) one can bypass the ragion validation.

TestHTTPProbeChecker fails on the Go1.7 release candidates. The
package's history show that this was the case for Go1.5 and Go1.6
as well.
The test depend on errors holding specific string values, behavior
not guarenteed in the standard library API, and causing new test
failures every minor Go release. Just look for an error rather than
trying to inspect it using string comparison. If we feel this
impacts coverage we can add more test cases.

Improve quota controller performance by eliminating unneeded list calls
Previously, when syncing quota usage, we asked each registered `Evaluator` to determine the usage it knows to track associated with a `GroupKind` even if that particular `GroupKind` had no associated resources under quota.
This fix makes it that when we sync a quota that just had only `Pod` related compute resources, we do not also calculate the usage stats for things like `ConfigMap`, `Secret`, etc. per quota.
This should be a significant performance gain when running large numbers of `Namespace`'s each with `ResourceQuota` that tracks a subset of resources.

Remove an unused logic. Also this prevents the KillPod() from failing
when the service file doesn't exist. E.g., it can be removed by garbage
collection in a rare case:
1, There are already more than `gcPolicy.MaxContainers` containers running
on the host.
2, The new pod(A) starts to run but doesn't enter 'RUNNING' state yet.
3, GC is triggered, and it sees the pod(A) is in an inactive state (not running),
and the it needs to remove the pod to force the `gcPolicy.MaxContainers`.
4, GC fails to remove the pod because `rkt rm` fails when the pod is running,
but it removes the service file anyway.
5, Follow up KillPod() call will fail because it cannot find the service file
on disk.
Also this is possible only when the pod has been in prepared state for longer
than 1 min, which sounds like another issue.

[GarbageCollector] Let the RC manager set/remove ControllerRef
What's done:
* RC manager sets Controller Ref when creating new pods
* RC manager sets Controller Ref when adopting pods with matching labels but having no controller
* RC manager clears Controller Ref when pod labels change
* RC manager clears pods' Controller Ref when rc's selector changes
* RC manager stops adoption/creating/deleting pods when rc's DeletionTimestamp is set
* RC manager bumps up ObservedGeneration: The [original code](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/replication/replication_controller_utils.go#L36) will do this.
* Integration tests:
* verifies that changing RC's selector or Pod's Labels triggers adoption/abandoning
* e2e tests (separated to #27151):
* verifies GC deletes the pods created by RC if DeleteOptions.OrphanDependents=false, and orphans the pods if DeleteOptions.OrphanDependents=true.
TODO:
- [x] we need to be able to select Pods that have a specific ControllerRef. Then each time we sync the RC, we will iterate through all the Pods that has a controllerRef pointing the RC, event if the labels of the Pod doesn't match the selector of RC anymore. This will prevent a Pod from stuck with a stale controllerRef, which could be caused by the race between abandoner (the goroutine that removes controllerRef) and worker the goroutine that add controllerRef to pods).
- [ ] use controllerRef instead of calling `getPodController`. This might be carried out by the control-plane team.
- [ ] according to the controllerRef proposal (#25256): "For debugging purposes we want to add an adoptionTime annotation prefixed with kubernetes.io/ which will keep the time of last controller ownership transfer." This might be carried out by the control-plane team.

Fix watch cache filtering
When serving watch events for a particular namespace, the watch cache filters out events from other namespaces by checking the etcd key of the event's object, and making sure it is prefixed with the root key for the namespace being watched.

This tightens the check to ensure the prefix match occurs on a path segment boundary.

Retry when apiserver fails to listen on insecure port
The apiserver will already continually retry when it fails to bind to the secure port. However, with the insecure port it does not retry, and any failures cause the apiserver to exit.
This change makes it so the api-server will retry on both insecure/secure ports.
A use-case for this change is for self-hosting the api-server, particularly when you are only running a single copy in your cluster. In some bootstrap and upgrade scenarios - it's necessary to replace/pivot from an existing api-server on the same host -- where you need a new copy running before tearing down the old (which is problematic when the api-server will try to bind to an in-use port and exit).
With the introduction of batch/v1 and batch/v2alpha1, any
