Updates verify.sh to track image name instead of ID and to support modifiable images at runtime (i.e. cert generation).
Add test-liberty-certificates project that generates dummy certificates in staging, then importing them into the Liberty image to emulate a BYO cert scenario.
Update projects pointing to old image refs openliberty/open-liberty:kernel-slim-ubi
Fixes https://github.com/OpenLiberty/ci.docker/issues/413
