Provide example when format string is rate limited

Here's an example log line in the new format:
    [RATE LIMITED] format string "open-conn-track: timeout opening %v; no associated peer node" (example: "open-conn-track: timeout opening ([ip] => [ip]); no associated peer node")
This should make debugging logging issues a bit easier, and give more
context as to why something was rate limited. This change was proposed
in a comment on #1110.
