Allow handlers earlier in a request flow to inject a UID for an object
This lets admission controllers specify a stable UID for an object prior to its creation. That lets the admission controller then record a reference to the object on another resource using that stable UID prior to the object being created. This would be a prerequisite for supporting quota reservations.

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.
Fixes: #21464

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.

Format apiserver options
Trivial change, code formatting only: it was hard to read long lines, and my editor was really slow when scrolling through them.

Certificate signing controller for TLS bootstrap (alpha)
The controller handles generating and signing certificates when a CertificateSigningRequest has the "Approved" condition. Uses cfssl to support a wide set of possible keys and algorithms. Depends on PR #25562, only the last two commits are relevant to this PR.

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.

Use Infof/Warningf when appropriate
When we use a format string, we should use Infof/Warningf instead
of Info/Warning

Delete redundant if condition
The case `containerStatus == nil` has already been checked just above. It's redundant here.

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.
