Description of problem:

To facilitate (hopefully) moving this to fedora hosted at some point down the track we need to remove redhat internal only addresses and certificates.

This will require:

- Removal of the internal topic repository addresses from the default topic.conf.
- Removal of the RH CA key from the keystore.
- Removal of internal source attribute in spec file.

Ideally the repository and source information should be changed to use public equivalents. A post install script should be provided for internal users which configures the correct repositories and imports the redhat key.
