- Change to packagespec results in package IDs that can use
  git tag refs, not just commit refs.

- This busts all caches, because of a change to the way we
  no longer traverse from tag refs to commit refs, due to
  the potential confusion this can cause.
- See https://github.com/hashicorp/packagespec/commit/fd54aea4827bb6cfd637c78a2ab6274111605330

  to be used for source IDs, begun in f130b940a8fbe3e9398225b08ea1d63420bef7b6
