FEATURE: change the --url argument with a path to repo
Kufair is not good at dealing with repos: access-token, url, users... these are complications which are not necessary at kufair level, scitrace-web is much better at it.
Therefore we should provide a path to a local copy of a repo. The folder needs to be a git repo because the url will be extracted from the .git/config
for the trace.
./kufair package create --repo=<path-to-repo> ...
