[Feature Request] Offer relay functionality

I don't know where to put this. If this is an inappropriate repository for this issue please close it and tell me where to request it.

This docker container already has all the functionality needed for relay operations I think. Please corretc me if I'm wrong. So not only obfs4 bridges, but also normal exit and non-exit relays. As a result I would like to have the option to specify the type of relay (bridge, middle/guard, exit) via enviroment variable and adjust the torrc config accordingly. The container already allows passing of custom variables through OBFS4V_variable. Renaming the prefix and offering to also change BridgeRelay 1 already would enable the functionality of an normal relay.

There currently is no official container available to host an tor relay on docker.
