This is part of the transition to using framework/log instead
of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
- moves these helper functions into e2e/framework/auth
- removes logging from helper functions
- in some cases explicitly returns errors that were implicitly
ignored/logged. In the situations where they should be ignored,
we explicitly check that the condition is met before ignoring it.
- fixes references of these methods to use the right package and
return values
