CDD CI improvements

What changes:

• Fix: CI deprovision-test-resources always runs now (even if Test CI's fail)

• Fix: Instead of force-creating expected Project, now just checks if it exists, if it doesn't it fails

• Improvement: Source Drupalsite for cloning uses a more comprehensive label, ci-clone-source

• Improvement: Site checking now times out after 20min (instead of 16min), logs and comments updated accordingly

• Fix: Removed needs from deprovision stage, as per gitlab reference, we do not need to run this stage out of order

• Remove composer.lock from repo
