    Increase and randomize healthcheck interval to avoid cpu congestion.

    All the healthcheck timers are triggered at the same time which causes
    cpu congestion. With the default interval of 30s this cause
    unnecessary stress on the environment.

    We increase the default interval and randomize the trigger to 3/4 of
    the timer. Tasks, on average and by default, should thus still be
    triggered every minute, but ranging from 15s to 1m45s.
