Support seperate versions for each module.

[matifali]

We need to bump the version for all modules or do some parsing to detect which modules have changed between tags.

It would be ideal if each module could have its versioning instead of the repo version tag.

@mafredri has some interesting ideas here.

After discussing with @mafredri, we can have tags like module-name/1.0.0

A similar release tagging is seen on moby/buildkit repo.
