The ShortTermStorageManager and related classes should live in their own package eventually and not within galaxy.web nor galaxy.managers as the short term storage microservices it's fairly independent and has way less dependencies than those other packages.
The ShortTermStorageManager is a manager and makes sense to have it live under galaxy.managers instead of galaxy.web.
It will also help reduce the dependency of the manager modules on web related stuff.
Fix:
```
test/unit/web_framework/framework/test_framework_base.py:4
/home/runner/work/galaxy/galaxy/galaxy root/test/unit/web_framework/framework/test_framework_base.py:4: PytestCollectionWarning: cannot collect test class 'TestWebapp' because it has a __init__ constructor
class TestWebapp(WebApplication):
```
Also:
- Use f-string.
- Simplify code using assert.
