vSphere provider - Getting node data by ip instead of uuid
To get the uuid we need the service to be running as root. This change
allows us to run the controller-manager and api server as non-root.

Adding SCSI controller type filter for vSphere disk attach
Hot plug of disks to a SCSI controller of type lsilogic doesn't work as expected. When a device is detached from the controller, it fails to remove the device from the /dev path which makes the subsequent attaches to the node to fail. With scsi controller types lsilogic-sas or paravirtual this seems to work well. This patch filters the existing controller for these types, and if it doesn't find one, it creates a new controller for disk attach.
This PR is dependent on https://github.com/kubernetes/kubernetes/pull/26658 (1st commit) also targeting this for 1.3

Removing name field from Member for compatibility with OpenStack Liberty
In OpenStack Mitaka, the name field for members was added as an optional field but does not exist in Liberty. Therefore the current implementation for lbaas v2 will not work in Liberty.

AWS/GCE: Spread PetSet volume creation across zones, create GCE volumes in non-master zones
Long term we plan on integrating this into the scheduler, but in the
short term we use the volume name to place it onto a zone.
We hash the volume name so we don't bias to the first few zones.
If the volume name "looks like" a PetSet volume name (ending with
-<number>) then we use the number as an offset. In that case we hash
the base name.

GCE provider: Create TargetPool with 200 instances, then update with rest
GCE provider: Create TargetPool with 200 instances, then update with rest
Tested with 2000 nodes, this actually meets the GCE API specifications (which is nutty). Previous PR (#25178) was based on a mistaken understanding of a poorly documented set of limitations, and even poorer testing, for which I am embarassed.
Also includes the revert of #25178 (review commits separately).

Lots of comments describing the heuristics, how it fits together and the
limitations.
In particular, we can't guarantee correct volume placement if the set of
zones is changing between allocating volumes.
Filters can't exceed 4k, and GET requests against the GCE API are also
limited, so these break down in different ways at different cluster
counts. Fix it by introducing an advisory node-instance-prefix
configuration in the GCE provider that can hint the
EnsureLoadBalancer/UpdateLoadBalancer code (and the firewall
creation/update code). If it's not there, or wrong (a hostname that's
registered violates it), just ignore it and grab the whole project.
Hot attach of disk to a scsi controller will work only if the
controller type is lsilogic-sas or paravirtual.This patch filters
the existing controller for these types, if it doesn't find one it
creates a new scsi controller.

AWS volumes: Use /dev/xvdXX names with EC2
We are using HVM style names, which cannot be paravirtual style names.
See
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/device_naming.html
This also fixes problems introduced when moving volume mounting to KCM.

refuse to create a firewall rule with no target tag
fixes#25145
This modification in gce.firewallObject() will return error when trying
to create or update firewall rule if no node tag can be found. Also add
unit test for this modification.
We had a long-lasting bug which prevented creation of volumes in
non-master zones, because the cloudprovider in the volume label
admission controller is not initialized with the multizone setting
(issue #27656).
This implements a simple workaround: if the volume is created with the
failure-domain zone label, we look for the volume in that zone. This is
more efficient, avoids introducing a new semantic, and allows users (and
the dynamic provisioner) to create volumes in non-master zones.
Fixes#27657

- replaces probeVolume with scsiHostRescan to scan hot attached disks
- fixes substring match of UUID returned from AttachDisk
- changes DetachDisk to take volumePath argument instead of diskID
- fixes delayed failure at mount rather than attach disk
- removes cloning of virtual disk in AttachDisk

AWS: support mixed plaintext/encrypted ports in ELBs via service.beta.kubernetes.io/aws-load-balancer-ssl-ports annotation
Fixes#26268
Implements the second SSL ELB annotation, per #24978
`service.beta.kubernetes.io/aws-load-balancer-ssl-ports=*` (comma-separated list of port numbers or e.g. `https`)
If not specified, all ports are secure (SSL or HTTPS).

LBaaS v2 Support for Openstack Cloud Provider Plugin
Resolves#19774.
This work is based on Gophercloud support for LBaaS v2 currently in review (this will have to merge first):
https://github.com/rackspace/gophercloud/pull/575
These changes includes the addition of a new loadbalancer configuration option: **LBVersion**. If this configuration attribute is missing or anything other than "v2", lbaas v1 implementation will be used.
Fixes#26268
Implements the second SSL ELB annotation, per #24978
service.beta.kubernetes.io/aws-load-balancer-ssl-ports=* (or e.g. https)
If not specified, all ports are secure (SSL or HTTPS).
Add ELB proxy protocol support via the annotation
"service.beta.kubernetes.io/aws-load-balancer-proxy-protocol". This
allows servers like Nginx and Haproxy to retrieve the real IP address of
a remote client.
Implements #25145
This modification in gce.firewallObject() will return error when trying

Instead of N pointers, we were returning N null pointers, followed by the real
thing. It's not clear why we didn't trip on this until now, maybe there is a
new server-side check for empty subnetID strings.
Instead of just rate limits to operation polling, send all API calls
through a rate limited RoundTripper.
This isn't a perfect solution, since the QPS is obviously getting
split between different controllers, etc., but it's also spread across
different APIs, which, in practice, rate limit differently.
Fixes#26119 (hopefully)
