Thanks Ben for reporting back.

Yeah the {{org.quartz.jobStore.misfireThreshold}} option is to configure this. However Quartz doesn't have a nice API to set that from Java API.
Getting the JobStore is not easy and the SPI interface doesn't expose this setter. Its only avail on specialized JobStore instances and whatnot.

So end users most often have to use a quartz.properties file to configure it and have the Camel Quartz Component pickup this quartz.properties file.
But that's the standard way with Quartz, so let's keep it as is.

> Quartz scheduler may by default try to catch up if a quartz consumer has been stopped for a while.
> Then when its started it may trigger a series of jobs due they were supposed to be triggered if the consumer has been always running.
> We should make it easy to configure an option to tell Camel to ignore those jobs.
> For example if you have a trigger to run every 5th second. And you pause a consumer for 2 hours. You may not want quartz to fire 12 * 60 * 2 jobs when its started to catch up for those 2 hours.
> Quartz itself may have an option you can configure on the job but it may not be obviously how to do this.
