Prepare resources in the GitHub action for test scripts

[jonct]

I expect that this will set up the appropriate networking for automated tests, as requested.

These steps are working here, in a fresh Ubuntu Server Live CD on VMware Fusion. I'll be watching for how they play out in GitHub's runner configuration.

FWIW I've lifted that setup into the action declaration, to keep it from cluttering otherwise clean tests in the script.

With apologies — that wasn't my remit — I've tacked on a second commit that applies this same separation of concerns to other resources like ZFS and exec bits.

Also I think apt-get update and upgrade are supposed to be GitHub's problem, rather than counting against everybody's usage individually? I could be wrong on that; I'm mostly a self-hosted GitLab guy.

I accidentally submitted this against main and instead of develop.

It's possible that all I'm missing right now is a proper dnsmasq.conf but right now we're WIP.

You can switch the into branch if you edit the PR

Hah! Right under my nose. I kept seeing only the title field appear, and wouldn't spot the pop-up. 🙄 Many thanks.

Thanks! As you can see I made a mess of it again :) sorry! But the setup does work now and without using dnsmasq. Maybe some iptables rules can be removed / simplified and they definitely should be moved again from the test script into the yaml.

Thanks a lot @jonct! Even though I did some cleanup and merged this into develop, feel free to suggest improvements :)

Niiiiiiiice! 💯 Full endorsement. No notes.
