This update for opi fixes the following issues:

Version 2.7.0

- Make repo parsing more stable and improve error handling
- Do not compress man page during build/install phase, but rather
  rely on the brp-scripts to pick the right compression format.

Version 2.6.0

- Move to global config in /etc/opi.cfg
- Check if desired repo is already added instead of relying on prefix
- Add config option use_releasever_var
