Prior this commit we only had support for username/password authentication in the koji integration. This wasn't particularly useful because this auth type isn't used in any production instance. This commit adds the support for GSSAPI/Kerberos authentication. The implementation uses kerby library which is very lightweight wrapper around C gssapi library. Also, the koji unit test and the run-koji-container script were modified so the GSSAPI auth is fully tested.
