new 9c14037ae fix: Fix garbage collection trait
9c14037ae is described below
commit 9c14037ae4e30465982f1d844c2a3e2eb1ddbe82
Author: Christoph Deppisch <cdeppi...@redhat.com>
AuthorDate: Fri Apr 12 17:03:46 2024 +0200
fix: Fix garbage collection trait
- Run garbage collection trait also in Integration initialization phase
- Fallback to minimal set of deletable types when auto discovery fails
(e.g. in OpenShift)
- Add some unit and E2E test
