The pkg/api/testing can be removed whem kubeadm splits into
its own repository.
The pkg/kubemark probably will remain as is for the foreseeable
future.

Updates RangeSize error message and tests for IPv6.
**What this PR does / why we need it**:
Updates the RangeSize function's error message and tests for IPv6. Converts RangeSize unit test to a table test and tests for success and failure cases. This is needed to support IPv6. Previously, it was unclear whether RangeSize supported IPv6 CIDRs. These updates make IPv6 support explicit.
**Which issue this PR fixes**
Partially fixes Issue #1443

Parse cluster-cidr only if it is specified
xref https://github.com/kubernetes/kubernetes/issues/53570#issuecomment-335943956
**What this PR does / why we need it**:
In iptables/proxier.go, there is code to check the length of the
CIDR and setup nat/iptables only if the length of the string is
greater than zero. However in PR #49087, strong validation was
added so kube proxy currently bails out and basically mandates
a valid cidr has to be specified. Let us go back to the earlier
behavior.

Avoid fetching entire discovery tree when possible
For specific commands, we use discovery to determine whether a particular resource is available.
We should avoid fetching the entire discovery tree to check a single resource group version. As the number of groups grows, the performance hit and potential to encounter an error also grows.

Release NodePorts at the end of test cases
**What this PR does / why we need it**:
#49098 reported a flake of HealthCheck NodePort leak and #49099 fixed it. I don't know why I forgot to check other Node Ports in the test cases. Though I haven't encountered such flake yet, it'd be good to release those Node Ports at the end of test cases to avoid flake.
