Fix overlong junit filename prefixes (2nd attempt)
This is followup for #30894.
Turned out that filename shortening I used isn't enough in some cases (scroll to the right):
```

Looks like we're have no choice here besides just using a hash as filename prefix.

AWS: More ELB attributes via service annotations
Replaces #25015 and addresses all of @justinsb's feedback therein. This is a new PR because I was unable to reopen#25015 to amend it.
I noticed recently that there is existing (but undocumented) precedent for the AWS cloud provider to manage ELB-specifc load balancer configuration based on service annotations. In particular, one can _already_ designate an ELB as "internal" or enable PROXY protocol.
This PR extends this capability to the management of ELB attributes, which includes the following items:
* Access logs:
* Enabled / disabled
* Emit interval
* S3 bucket name
* S3 bucket prefix
* Connection draining:
* Enabled / disabled
* Timeout
* Connection:
* Idle timeout
* Cross-zone load balancing:
* Enabled / disabled
Some of these are possibly more useful than others. Use cases that immediately come to mind:
* Enabling cross-zone load balancing is potentially useful for "Ubernetes Light," or anyone otherwise attempting to spread worker nodes around multiple AZs.
* Increasing idle timeout is useful for the benefit of anyone dealing with long-running requests. An example I personally care about would be git pushes to Deis' builder component.

[e2e density test] Fix unnecessary Delete RC requests when not running latency test
As the following code block
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/density.go#L666-L670
shows, after running each density test case, it will attempt to delete "additional replication controllers" even though there is **no additional replication controller**.
When we are not running latency test, API Server will return "404 error code". So, I propose to move the above code block inside thedetermine statementsif `itArg.runLatencyTest{ }` , looks like:
```
if itArg.runLatencyTest {
...
for i := 1; i <= nodeCount; i++ {
name := additionalPodsPrefix + "-" + strconv.Itoa(i)
c.ReplicationControllers(ns).Delete(name, nil)
}
}
```
In this way, removing RC will be executed only if we set `itArg.runLatencyTest` to be `true`. It can avoid post some necessary requests to API Server.

Impersonate user extra
Second commit builds on https://github.com/kubernetes/kubernetes/pull/30803.
This adds a restriction to `user.Info.Extra`, keys must be lower case. This is because HTTP headers are case insensitive, so we can't be sure that we'll get the right case through proxies or even Go (the go library capitalizes after dashes). I don't think anyone is using them, if they are, they'll need to update to properly plumb through an impersonation flow.

Updating version check for etcd
<!-- Thanks for sending a pull request! Here are some tips for you:
1. If this is your first time, read our contributor guidelines https://github.com/kubernetes/kubernetes/blob/master/CONTRIBUTING.md and developer guide https://github.com/kubernetes/kubernetes/blob/master/docs/devel/development.md
2. If you want *faster* PR reviews, read how: https://github.com/kubernetes/kubernetes/blob/master/docs/devel/faster_reviews.md
3. Follow the instructions for writing a release note: https://github.com/kubernetes/kubernetes/blob/master/docs/devel/pull-requests.md#release-notes
-->
**What this PR does / why we need it**:
Currently, if you `make build`, etcd is not properly version checked because `etcd -version` does multi-line output. This output cannot be version compared. This small change fixes that.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

AWS: Support HTTP->HTTP mode for ELB
**What this PR does / why we need it**:
Right now it is not possible to create an AWS ELB that listens for HTTP and where the backend pod also listens for HTTP.
I asked @justinsb in slack and he said that this seems to be an oversight, so I'd like to use this PR as a step towards solving this.
**Special notes for your reviewer**:
I've only added a simple unit test. Are any integration tests needed? I'm not familiar with the code base.

Fix caching of go dirs during build
Sometimes when you press `^C` during `make` the subsequent attempt to run `make` hangs due to zero-sized cache file for `ALL_GO_DIRS` var in Makefile.generated_files:
```
vagrant@devbox:~/work/kubernetes/src/k8s.io/kubernetes (master *%) $ KUBE_JUNIT_REPORT_DIR=/tmp/art KUBE_COVER=y make test
# hangs...
^CMakefile:279: recipe for target 'generated_files' failed
make: *** [generated_files] Interrupt
vagrant@devbox:~/work/kubernetes/src/k8s.io/kubernetes (master *%) $ ls -l .make/all_go_dirs.mk
-rw-rw-r-- 1 vagrant vagrant 0 Aug 18 15:03 .make/all_go_dirs.mk
```
Corresponding process subtree looks like the following:
```
└─make test
└─make -f Makefile.generated_files generated_files
└─bash -c grep --color=never -l '+k8s:deepcopy-gen=' | xargs -n1 dirname | sort -u
├─grep --color=never -l +k8s:deepcopy-gen=
├─sort -u
└─xargs -n1 dirname
```
Let's remove the cache file if `cache_go_dirs.sh` gets interrupted.
