ci: Add unit tests to compare CLI and OpenAPI

The goal here is to ensure that CLI and OpenAPI both behave as closely
as possible, and also that they behave as expected.

Leveraging the reorganization of the code, we can now compare two
VmConfig structures generated from one CLI entry on one side, and from
an OpenAPI entry (JSON payload) on the other side.

Fixes #535
