CNV-40881: kubevirt, e2e, add test for advanced multinet

[qinqon]

What this PR does / why we need it:
This change add a test to start a kubevirt hosted cluster with just secondary interface as primary network and start a companion dnsmasq pod attached to that network that acts as dhcp server, gateway and masquerade. The test only has one worker so this works as expected.

TODO:

• The default passthrough ingress service is pointing to the VM but default network cannot access that IP, either make it go over dnsmasq and redirect the https traffic to the VM there or connect the VM to the underlay (not sure if this would work though).

Now is possible to run different nodepools at different hosted cluster and those are run in parallel too.

@qinqon re #3902 (comment) ... it's two fields (Compute, RootVolume) to filter, which you can do with a one-liner in cmpopts.IgnoreFields(hyperv1.KubevirtNodePoolPlatform{}, "Compute", "RootVolume"). Did you check what the output looks like when the test fails for real? That is the real issue - when the test fails in a way we expect, the output of Ginkgo is very, very hard to read. The structured diff out of cmp is simple.

I won't force you to but I really think you would benefit from comparing the output of the test when it fails the way you expect between the two approaches.

[qinqon]

cmpopts.IgnoreFields(hyperv1.KubevirtNodePoolPlatform{}, "Compute", "RootVolume")

This means we have to maintain this in case new fields are added, I think is not worth it.

if the dnf install -y iptables dnsmasq procps-ng step in the dns pod turns out to be a source of pain the future (with repo outages or long install times), then we'll create our own dnsmasq container for this test that has these tools pre-baked in.
