Matrix chat rooms don't scale well #43

Result of the stress testing of Matrix server revealed that with increasing number of participants in the channel message delivery time increases exponentially. That's a problem for our proposed broadcast channel where Balance Proofs are broadcasted and Monitoring servers actively listen for messages sent to the channel.

Ideas:

• submit BP via direct message to MS. This would require some sort of MS discovery (can be done in a channel)
• split broadcast channels and use naming schema i.e. <chain_id>_<token_network_address>

TODOS:

• decide on how to avoid using broadcast rooms (use service discovery?)
• create metrics for proposed protocol
• decide which naming schema for the broadcast channels will be used
