Golang subversion vcs

[Luke Mauldin]

I see the latest (Go 1.17.X) releases support Subversion modules but I cannot figure out how to get the `go get` command to pull in a tagged subversion module. Subversion repo layout

- tags

  - contracts

    - configcontracts

      - v2.8.1

- trunk

  - contracts

     - configcontracts

        - go.mod file with module {HOSTNAME}/svn/testrepo/trunk/contracts/configcontracts

I tried multiple different module definitions in the go.mod file along with different go get commands.  I was able to get go get to work with an "invalid version" where the go.mod file lists:

XXXXXX/svn/testrepo/tags/contracts/configcontracts.svn v0.0.0-XXXXX

But obviously that isn't using versions (ie. v2.8.1) like Git.  Is it possible that there is a bug in the go get VCS for Subversion that I need to support or does someone else have other recommendations?
