Merge ~syntroniks/maas:cps-pdu-power-driver into maas:master

Hi all,

This is my first contribution to a Canonical project. I have included the desired functionality as well as python tests associated.

If there is any more documentation or demonstration of functionality required, please let me know. I would be happy to provide it.

The specific device this functionality is being developed for is the CyberPower PDU81007

Inline nit/questions, looks good elsewhere though.

I believe I have addressed your comments so far.

Most recent review just seems to need a file reformat, nothing major

I'm seeing some test failures that I do not think are related to my code. Can you share what may still be holding up this merge?

Thanks :)

Needs to run `make format`

I have done so and do not see any changes:

nothing to commit, working tree clean

That's using an older version of black, which was bumped to 23.1 recently. Can you try rebase master and then make format? There might be a minor formatting change to be done
