- 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.
GetGPUDevicePluginImage() was called in some e2e node test only.
So it is not worth keeping the function as a part of e2e test
framework. This moves GetGPUDevicePluginImage() to the e2e node
test for code cleanup.
