vSphere Cloud Provider Implementation
This is the first PR towards implementation for vSphere cloud provider support in Kubernetes (ref. issue #23932).
When vSphere cloud provider object is instantiated, the VM name of the
Node where this object is being create in needs to be set. This patch
also includes vSphere as part of the cloud provider package.
This patch includes implementation for the following Instance object
interfaces:
* NodeAddresses
* ExternalID
* InstanceID
Also minor refactoring in overall Instance implementation.

AWS: Add support for ap-northeast-2 region (Seoul)
This PR does:
- Support AWS Seoul region: ap-northeast-2.
Currently, I can not setup Kubernetes on AWS Seoul.

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.
This is a better abstraction than passing in specific pieces of the
Service that each of the cloudproviders may or may not need. For
instance, many of the providers don't need a region, yet this is passed
in. Similarly many of the providers want a string IP for the load
balancer, but it passes in a converted net ip. Affinity is unused by
AWS. A provider change may also require adding a new parameter which has
an effect on all other cloud provider implementations.
Further, this will simplify adding provider specific load balancer
options, such as with labels or some other metadata. For example, we
could add labels for configuring the details of an AWS elastic load
balancer, such as idle timeout on connections, whether it is
internal or external, cross-zone load balancing, and so on.

The previous logic was incorrect; if we saw two untagged security groups
before seeing the first tagged security, we would incorrectly return an
error.
Fix#23339
AWS has soft support limit for 40 attached EBS devices. Assuming there is just
one root device, use the rest for persistent volumes.
The devices will have name /dev/xvdba - /dev/xvdcm, leaving /dev/sda - /dev/sdz
to the system.
Also, add better error handling and propagate error
"Too many EBS volumes attached to node XYZ" to a pod.
We have previously tried building a full cloudprovider in e2e for AWS;
this wasn't the best idea, because e2e runs on a different machine than
normal operations, and often doesn't even run in AWS. In turn, this
meant that the cloudprovider had to do extra work and have extra code,
which we would like to get rid of. Indeed, I got rid of some code which
tolerated not running in AWS, and this broke e2e.
