Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. ... - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356) ... Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.
