I'm moving/deleting some tests to make an upcoming RESTClient refactor
PR cleaner.
- TestDoRequestBearer is redundant to
pkg/client/transport.TestBearerAuthRoundTripper
- Added a case to pkg/client/transport.TestBasicAuthRoundTripper to
cover what TestDoRequestWithoutPassword was testing
- Moved TestSetsCodec, TestRESTClientRequires,
TestValidateHostParameter to helper_test.go since they were really
testing helper functions and not the RESTClient directly.
- Modified TestValidateHostParameter during the moved to just use
DefaultServerURL instead of creating a client.
