cue modules dependency management

[cueckoo]

Originally opened by @hi-wayne in cuelang/cue#434

In the cue, the capacity of language can be expended via import. However, there was not a good tool to do dependent management, and it`s usually dependent on saved files in local “cue.mod pkg”. Here come a strong needs of version management since I want to do dependent download which is similar to “go mod” in a large scale cooperation situation. Thus similar activities is planned here and then raise a pr. What about opinions?

There is a cue mod sub command planned but not scheduled (afaik)

More discussion can be found in #409

Thanks for raising this @hi-wayne. I've just opened cuelang/cue#851 that directly addresses this question, so I'll mark this as closed and we can continue discussion there.
