Use mCPU as CPU usage unit, add version in PerfData, and fix memory usage bug.
Partially addressed #24436.
This PR:
1) Change the CPU usage unit to "mCPU"
2) Add version in PerfData, and perfdash will only support the newest version now.
3) Fix stupid mistake when calculating the memory usage average.

Enforce --max-pods in kubelet admission; previously was only enforced in scheduler
This is an ugly hack - I spent some time trying to understand what one NodeInfo has in common with the other one, but at some point decided that I just don't have time to do that.

Intial draft on SeedProvider docs
Alsa more documentation. We need to reference the config section in the example docs. There are multiple PRs open in those docs, so at this point I do not want to make a mess.
Let me know if there are docs standard template that will make this more pretty.

Removing KUBE_API_VERSIONS from our test scripts
We dont need to specify them.
Its an unnecessary extra change that people have to make while adding a group.
We also need this change for ubernetes.

This adds a poll-and-timeout procedure after the pod is
started, to make sure the post-start hooks execute when the
container is actually running.
This is a temporal workaround for implementing post-hooks,
a long term solution is to use lifecycle event to trigger
those hooks, see https://github.com/kubernetes/kubernetes/issues/23084.
Also this fixes a bug of getting container ID for a non-running
container when running pre-stop hook.
This is implemented via touching a file on stop as a hook in the systemd
unit. The ctime of this file is then used to get the `finishedAt` time
in the future.
In addition, this changes the `startedAt` and `createdAt` to use the api
server's results rather than the annotations it previously used.
It's possible we might want to move this into the api in the future.

Disable travis on master.
There's no need for it, and it's blocking merges. Until we've got the munger ignoring travis, this should patch the problem.

WIP: Proposed new PR release note template.
Initial template proposal - needs work to coexist with labels:
## ATTENTION - Release Note ack required!
Use the below `release-note` block to explain your change. Valid inputs include:
**"title"** - the release note is the title of the PR
**"none"** - No release note needed for this PR
_freeform text_ - Describe your change as a summarized release note
```release-note
...release-note block...
```
Second template proposal - replaces labels:
## ATTENTION - Release Note ack required!
Update the below named `release-note-needed` block to one of:
**\`\`\`release-note**
**\`\`\`release-note-action-required**
**\`\`\`release-note-none**
Then describe your change as a summarized release note within the block.
```release-note-needed
...release-note block...
`line` 2

Add tests to watch behavior in both protocols (http and websocket)
against all 3 media types. Adopt the
`application/vnd.kubernetes.protobuf;stream=watch` media type for the
content that comes back from a watch call so that it can be
distinguished from a Status result.

Default conversion for byte slices is incorrect
Nil slices are getting allocated, which is incorrect and changes
behavior in some cases.

Add timeout to e2e network connectivity checks
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.

jenkins: Allow configuration of release bucket
This allows others to leverage the existing E2E code to test some

All clients under ClientSet share one RateLimiter.
Currently we create a rate limiter for each client in client set. It makes the reasoning about rate limiting behavior much harder. This PR changes this behavior and now all clients in the set share single rate limiter. Ref. #24157

Rackspace improvements (OpenStack Cinder)
This adds PV support via Cinder on Rackspace clusters. Rackspace Cloud Block Storage is pretty much vanilla OpenStack Cinder, so there is no need for a separate Volume Plugin. Instead I refactored the Cinder/OpenStack interaction a bit (by introducing a CinderProvider Interface and moving the device path detection logic to the OpenStack part).
Right now this is limited to `AttachDisk` and `DetachDisk`. Creation and deletion of Block Storage is not in scope of this PR.
Also the `ExternalID` and `InstanceID` cloud provider methods have been implemented for Rackspace.

First pass at a GKE large cluster Jenkins job
Runs a 1000 node GKE parallel e2e test. On demand only. We'll add more

Add mpio support for iscsi
This allows the iscsi volume to check if a iscsi device belongs to a mpio device
If it does belong to the device then we make sure we mount the mpio device instead of
the raw device.
The code is based on the current FibreChannel volume support for mpio
example
/dev/disk/by-path/iqn-example.com.2999 -> /dev/sde
Then we check
/sys/block/[dm-X]/slaves/xx
until we find the [dm-X] containing /dev/sde and mount it
Additional work that can be done in future
1. Add multiple portal support to iscsi
2. Move the FibreChannel volume provider to use the code that has been extracted
