* Rework node stats a bit. Related protocol PR - https://github.com/livekit/protocol/pull/1023 - Make a config for node stats measurements. Wanted to put the config in `routing` package, but a circular dependency forced me to put in config.go - Make rate calculations explicit, i. e. requested via config. Previously, it had some odd checks to decide when to calculate rate and it would have been calculating over different windows. - Report signal/data channel bytes every 5 seconds to stats collection module. Previously, it was doing it every 30 seconds and that meant some windows could have had a large spike NOTE: Still need to think about this for load calculations as a large number of participants leaving could flush in a small window and that could report a large spike in bytes/packets. Maybe need to ignore signal bytes for load calculation? * deps * use default node stats config if given config is nil * split out node stats into a struct for re-use * update config
