Check for vcs tag when scanning path for packages

**Is your feature request related to a problem? Please describe.**
I manage 100+ private packages and having to specify them individually in `statis.json` is a chore in and of itself.

**Describe the solution you'd like**
Since the behavior for a `path` repository is to scan for packages, I think it is helpful to further check if it is also a vcs with a tag and utilize the tag as version. This could be an additional flag so that we can retain the current `path` behavior

**Describe alternatives you've considered**
I could scan the repos and generate the json for `satis.json`
