Title: Add a more friendly error message when the repo file is missing

After trying rpm-ostree, I didn't fully understand that the "repos" option required a file in the same directory as the json file, and tought this was refering to the existing repository. So this PR add a better error message, saying that a file is missing and where it is looking for, rather than a cryptic yum error.
