Proposed Commit Message

chore: bump ci dependency versions

- use canonical/lxd in integration test
- optimize integration test to run faster

Additional Context

#5658

I would prefer to keep unit tests on earliest ubuntu, not latest. Us devs are generally all running latest, so I think it helps with additional coverage. We have the 'lowest supported' job, but it winds up being more of an approximation.

Tests currently run on Jammy which is neither earliest nor latest. Would you rather we drop the release it from Jammy down to Focal?

My only counterpoint is that as part of Canonical we're better equipped to dogfood new versions so I'd lean towards early adoption since our internal CI infrastructure gets us unittest coverage as part of package build for integration testing.

That said, I really don't think it matters what version of Ubuntu we're on, because for unit tests we use actions/setup-python, and install tox via pip, so I don't see any system dependencies being used anyways.

Good point, +1.

One question and one ask inline, but +1 either way.
