Generate and handle a gl_repository param to pass around components

This new param allows us to share project information between components
that don't share or don't have access to the same filesystem
mountpoints, for example between Gitaly and Rails or between Rails and
Gitlab-Shell hooks. The previous parameters are still supported, but if
found, gl_repository is prefered. The old parameters should be deprecated
once all components support the new format.
