Feature request: Generate docket files for your repo automatically

[levinem]

Is your feature request related to a problem? Please describe. Writing a set of docket files is currently a manual process. It would be great if, when running go test, it could trigger docket to find the set of dependencies using the go.mod file, see if those dependencies have existing docket files, and generate docket files for the current repo automatically based on the existing docket files.

Describe the solution you'd like I think there should be a dkt command like dkt generate that generates docket files for you based on the repo dependency tree. This command could be called automatically by running go get.
