Issue-356: Drop unnecessary Authorizer

[ibihim]

What

• Remove non resource attributes generator.

Why

• We might not need it. Normal requests already have the given form of only "path", "verb" and "user".
• It might be more secure, as we don't mask other attributes.

Notes

• It is theoretically a regression.
• Ref: https://github.com/brancz/kube-rbac-proxy/issues/356

[ibihim]

@ibihim add log output before change, to show an exemplary resource attribute for that case.

Make a (manual) test for what would happen, if you have a resource request.
