> ActionScheduler now sleeps only 1 second between scans while it was sleeping for 10 seconds before. We should make it configurable where user can set the delay. Users with slower DB would rather have ActionScheduler not work so aggressively.
> Currently, it is hard coded to 1 second.
> {code}
> bindConstant().annotatedWith(Names.named("schedulerSleeptime")).to(1000L);
> {code}
> Lets add a config parameter to {{ambari.properties}} -  {{server.execution.scheduler.wait}} and default should be 1 second. If the value is more than 60 second then it should automatically set to 60 second with a log saying so.
