gateway/cmd: generate CacheGroup for user direct runs

Since the user direct runs all belong to the same run group (the user id) all
the user direct runs will share the same caches. To distinguish between the
different caches we need to use something in addition to the user id. In this
case we are usin the local repo uuid generated by the direct run start command.
