Document Snowflake broker implementation
We should document how the current Snowflake implementation distributes Snowflake proxies to clients that is in need of them.
Once we have specified how the current implementation works, we should figure out if there are things we would like to change before we can start shipping Snowflake in an alpha state to users.
- Look at broker code in the Snowflake repository.
- Document current behavior with long-polling clients waiting to get handed a proxy.
- Let's discuss if this design have any weaknesses we would like to address.
One weakness here could be that currently the broker nor client DOES NOT pass information about which bridge/relay to connect to, but this bridge/relay host is hardcoded in both the Go and JS proxy code.
