Find and clean up unused image streams

Look into and possibly remove possibly unused image streams on devtest/prod.

**Purpose**
- Reduce confusion
- Reduce resource usage

**Acceptance Criteria**
- [ ] See if image streams on dev/test/prod are actually being used
- [ ] It seems like the `alcs-portal-api`, `alcs-migrate`, and `backup-container` image streams in the tools namespace are also unused
- If deemed unnecessary
- [ ] Remove unused streams
- [ ] Fix reference to deleted streams in config files

**Additional context**
- It seems like some of the base config files are referencing dev/test/prod streams, but none of the patch values do. This leads me to believe that these used to be used, but everything was switched over to use the tools image streams, and the dev/test/prod streams were just never cleaned up.

Inspect the base config files and patch values for references to dev/test/prod image streams, then compare those references with the streams in the tools namespace. Check whether alcs-portal-api, alcs-migrate, and backup-container are used in each environment; done means unused streams and their stale config references are removed.
