Pull request overview
This PR implements support for the lp-test backend in the craft testing framework. The lp-test backend uses OpenStack for running spread tests, as an alternative to the existing local lxd-vm backend or CI backend.
Key changes:
- Added automatic detection of lp-test backend when
LP_TEST_ACCOUNTenvironment variable is set - Implemented OpenStack backend configuration for lp-test with system image mappings for Ubuntu 20.04, 22.04, and 24.04
- Extended spread models to support OpenStack-specific fields (endpoint, account, key, location, plan, halt_timeout) and image specifications per system

IIUC halt_timeout applies to all backends. What about the rest of these?
The main reason I ask is because of https://github.com/lengau/spread-schema

Can lp-test use the ubuntu-minimal images?

What's the expected behaviour if we had:

The comment on line 222 is now disconnected from the conditional on line 223. Move the comment to line 223 (directly above the if statement) to maintain clarity.

The variable entry is declared before the isinstance check but only used in the else branch (line 188 onwards). Move the declaration to line 187 (after the continue statement) to scope it closer to its usage.
