IPv6 support for getting node IP

As part of ChooseHostInterface(), it will call a function to try to get the
global IP for the host, by looking at all the system interfaces and select
the first IP that is not a loopback, link-local, or point-to-point IP.

This commit does the following:

- Allows IPv6 non-local IPs to be selected.
- IPv4 takes priority (checks all interfaces for IPv4 addresses and
  then checks all interfaces for IPv6), for backward compatibility.
- Adds UTs for code coverage (was no coverage of underlying function),
  increasing from 62% to 85%.
- Improved logging and reporting for error conditions.
- Minor renaming of functions and variables for readability.



**What this PR does / why we need it**:
This will be part of several PRs to add IPv6 support in apimachinery area for use by Kubernetes. It partially fixes the issue.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: xref #44848

This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.

Most code in the staging/ directory is authoritative, i.e. the only copy of the code. You can directly modify such code. However the packages in staging/src/k8s.io/client-go/pkg are copied from pkg/. If you modify the original code in pkg/, you need to run hack/godep-restore.sh from the k8s root directory, followed by hack/update-staging-client-go.sh. We are working towards making all code in staging/ authoritative.

The vendor/k8s.io directory contains symlinks pointing to this staging area, so to use a package in the staging area, you can import it as k8s.io/<package-name>, as if the package were vendored. Packages will be vendored from k8s.io/<package-name> for real after the test matrix is converted to vendor k8s components.
