this is mainly to ensure integration tests (which all end in _test)
are properly bossed around for their imports
I had to adjust some of the _test files to adhere to existing
reverse_rules specified elsewhere
yaml has comments, so we can explain why we have certain rules or
certain prefixes
for those files that weren't already commented yaml, I converted them to
yaml and took a best guess at comments based on the PRs that introduced
or updated them
Integration tests imported e2e test code and the dependency made two drawbacks:
- Hard to move test/e2e/framework into staging (#74352)
- Need to run integration tests always even if PRs are just changing e2e test code
This enables import-boss check for blocking such dependency.
