(was: Here is a patch for quartz2 component. I assume, that similar issue exists in quartz component as well. At least, source code looks similar. But, honestly, I have not tested it yet.)

> When quartz/quartz2 component used in cluster mode with JDBCJobStore it gets trigger options (cron expression or simple trigger repeat interval and repeat count) provided in component's URI and stores them into DB.
> When application runs next time, it uses stored values from DB and ignores (possibly changed) ones from URI.
> It is inconvenient in production environment to alter values in database every time we deploy a new version of the application with changed schedule. Especially, when we have bunch of clustered timers in several application modules, using same DB. Desirable behavior is to check trigger options in DB and reschedule quartz job when they changed.
> I created a patch with unit test to illustrate this issue. The test prepares DB, than creates application context twice with different cron expressions in configuration xml. Both times it retrieves back the cron expression, accessing it via trigger (so, using value stored in DB). After that it asserts that two cron expressions are not equal.
> You can check, that the test fails with old version of org.apache.camel.component.quartz2.QuartzEndpoint#addJobInScheduler method and passes with new one. Patched version of method compares existing trigger options with new ones and reschedule job if they changed.
> So far I only created test for changed cron expression and quartz2 component.
