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.

@luxas these changes seem a bit aggressive but seems reasonable given the compatibility expectations for kubeadm.

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.

It is possible that by the time we check for multiattach
error on node, the reconciler loop may not have processed second
volume and hence we are going to retry for multiattach error
on node before giving up and marking the test as failed.

[GCE kube-up] Allow creating/deleting custom network

From https://github.com/kubernetes/test-infra/issues/4472.
This is the first step to make PR jobs use custom network instead of auto network (so that we will be less likely hitting subnetwork quota issue).
The last commit is purely for testing out the changes on PR jobs. It will be removed after review.

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.
