[QE] Move config test from e2e to integration

[jsliacan]

Consider which parts of config.feature are still relevant and retain those as part of a new integration test.

Add checks:

• if monitoring is enabled, memory requirement is 14GiB
• if some of the preflight checks aren't satisfied, and setup --check-only is run, then start fails. This is rectified by running a full setup command.
