Problem/Motivation
It's been reported both in core and contrib that some test jobs fail due to DB not being available (?)
Core
PHPUnit
https://git.drupalcode.org/issue/drupal-1959304/-/jobs/573143
https://git.drupalcode.org/project/address/-/jobs/616657
Nightwatch
https://git.drupalcode.org/issue/drupal-3324560/-/jobs/629098
Contrib
https://git.drupalcode.org/project/cdn/-/pipelines/75330
Steps to reproduce
Proposed resolution
Add CI_DEBUG_SERVICES=true to .gitlab-ci.yml so we can get detailed information on what's happening in the database from a test that will fail.
Revert the change as soon as we find one job that will fail due to this
