We emit a debug log message whenever a child circuit breaker trips (in
ChildMemoryCircuitBreaker#circuitBreak(String, long)
) but we neveremit a log message when the parent circuit breaker trips. As this is
more likely to happen with the real memory circuit breaker it is not
possible to detect this in the logs. With this commit we add a log
message on the same log level (debug) when the parent circuit breaker
trips.
