[e2e service] Fix CleanupGCEResources for regional test
*What this PR does / why we need it**:
From https://k8s-testgrid.appspot.com/google-gke-staging#gke-staging-1-8-1-9-upgrade-regional-cluster&width=20, regional cluster test is failing because the GCE resource cleanup function attempts to parse region from `--gcp-zone` while regional cluster only set `--gcp-region`.
This PR pipes region into the cleanup function as well. This will need to be cherrypicked to 1.8 and 1.9.

note that we don't change the behaviour of kubectl.
For example it won't scale new resources. That's the end goal.
The first step is to retrofit existing code to use the generic scaler.

Hit ILB endpoint in e2e test
**What this PR does / why we need it**:
During the ILB e2e networking test, a pod is created and curls the ILB's IP address, validating that the load balancer correctly routes traffic to the K8s service. Test will also hit the external LB endpoint after switching from ILB->ELB, validating no GCE conversion issues going from ILB to ELB.
This does not validate that the load balancer is accessible externally to the cluster (but on the same network).

Add brackets around IPv6 addrs in e2e test IP:port endpoints
There are several locations in the e2e tests where endpoints of the
form IPv6:port use IPv6 addresses directly, without surrounding brackets.
Brackets are required around IPv6 addresses in this case, in order to
distinguish the colons in the IPv6 address from the colon immediately
preceding the port.
Also, wherever the curl command might be used with an IPv6 address
surrounded in brackets, the "-g" argument is added to the curl
command line arguments so that the brackets can be interpreted
correctly.
fixes#52746
**What this PR does / why we need it**:
This PR adds brackets around IPv6 addresses when they appear as part of an IPv6-addr:port endpoint
in the e2e tests. This is needed because any connections that attempt to use IPv6-addr:port
endpoint without brackets surrounding the IPv6-addr will fail.
