Allow stress testing E2E tests with PostgresDB (#46065)

* Modify the E2E stress test workflow to allow running PostgresDB

* Fix syntax

* Add qa_db to workflow summary

* Only run necessary containers

* Fix QA DB snapshots running when QA_DB_ENABLED=false

* Use more generic option that's not only specific to postgres
