M. J. Fromberger b6eabd4038 util/eventbus: allow logging of slow subscribers (#17705)
Add options to the eventbus.Bus to plumb in a logger.

Route that logger in to the subscriber machinery, and trigger a log message to
it when a subscriber fails to respond to its delivered events for 5s or more.

The log message includes the package, filename, and line number of the call
site that created the subscription.

Add tests that verify this works.

Updates #17680
