Integration with Packit

Packit service builds everything in Copr under the packit username. While previously the access list was maintained Packit-side, newly Packit users need to configure what upstream projects (GitHub) can build (through the Packit user) in configured copr project.

New options:

• $ copr create --packit-forge-project-allowed github.com/username/projectname
• $ copr modify --packit-forge-project-allowed github.com/username/projectname
