Option for separate media repo url

[tezlm]

I use matrix-media-repo, so I need to be able to upload to a separate address instead of the main homeserver address.

I can set the address to the public-facing url instead of localhost, but that would cause unnecessary overhead.

You should just have an internal (non-tls) listener in your reverse proxy, otherwise the bridge would need advanced custom routing capabilities to support other types of workers
