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
```

Default conversion for byte slices is incorrect

Nil slices are getting allocated, which is incorrect and changes

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

This job is no longer producing a useful signal. http://kubekins.dls.corp.google.com/ shows that the last pass was nearly two months ago. I would like to disable the job until someone has the chance to fix it so we are not wasting jenkins resources, contributing to system instability.

Make fake client actions use fully qualified resource

The output of a versioned clientset is version object. The fake client used to assume only internal objects will be returned. This PR removes this assumption by making fake actions initialized with a fully qualified resource instead of a resource string.

We have to regenerate fake clients in release_1_2 clientset to let it compile. For the test fakes, we are breaking the backwards compatibility promise.

Part of #24155.
