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.

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.

This commit adds logic for allocating and associating a public IP, if the `—load-balancer-ip` option is not used. It will do proper management of IP’s that are allocated by this provider, so IP’s that are no longer needed/used will also be released again.
Additionally the provider can now also work with CloudStack projects and advanced (VPC) networks.
Lastly the Zone interface now returns an actual zone (supplied by the cloud config), a few logical errors are fixed and the first few tests are added.
All the functionality is extensively tested against both basic and advanced (VPC) networks.

openstack: Autodetect LBaaS v1 vs v2
```release-note
* openstack: autodetect LBaaS v1/v2 by querying for available extensions. For most installs, this effectively changes the default from v1 to v2. Existing installs can add "lb-version = v1" to the provider config file to continue to use v1.
```

This removes the need to manually specify the version in all but unusual
cases.
For most installs this will effectively flip the default from
v1 (deprecated) to v2 so conservative existing installs may want to
manually configure "lb-version = v1" before upgrading.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.

TestLoadBalancer() test v1 not v2
TestLoadBalancer() should test v1 and TestLoadBalancerV2() test v2, but In TestLoadBalancerV() there are codes:
cfg.LoadBalancer.LBVersion = "v2"

Information is opposite to real meaning to express
master is not equal to expectedMaster, the meaning should be the master is unexpected:

AWS: Added experimental option to skip zone check
This pull request resolves#28380. In the vast majority of cases, it is appropriate to validate the AWS region against a known set of regions. However, there is the edge case where this is undesirable as Kubernetes may be deployed in an AWS-like environment where the region is not one of the known regions.
By adding the optional **DisableStrictZoneCheck true** to the **[Global]** section in the aws.conf file (e.g. /etc/aws/aws.conf) one can bypass the ragion validation.
This allows the user the set "working-dir" in their vsphere.cfg file.
The value should be a path in the vSphere datastore in which the
provider will look for vms.

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.
