- test/e2e/framework/*.go should have very minimal dependencies.
We can enforce that via import-boss.
- What each test/e2e/framework/* sub-package uses is less relevant,
although ideally it also should be as minimal as possible in each case.
Enforcing this via import-boss ensures that new dependencies get flagged as
problem and thus will get additional scrutiny. It might be okay to add them,
but it needs to be considered.
