[I] Ability to use timezones when using quartz component and CronJob strategy [camel-k]

["lsergio (via GitHub)" <gi...@apache.org>]

lsergio opened a new issue, #5121:
URL: https://github.com/apache/camel-k/issues/5121

   ### Requirement
   
   Consider the scenario where I set up an Integration with the following endpoint:
   
   `from("quartz://groupName/timerName?cron=* 10-12 * * *&trigger.timeZone=America/Sao_Paulo")`
   
    This is supposed to run everyday from 10 to noon on Sao Paulo timezone.
   
   As I create the integration in my cluster, it will create a CronJob with the 10-12 schedule. However, CronJobs run on the k8s node timezone, which in my case is UTC. So the integration would run with a 3-hours offset.
   
   ### Problem
   
   I would like to have my end users select the timezone they wish to run theirs jobs, but with the limitation I will either force them to use UTC, or configure my cron trait with `fallback: true` to support timezone.
   Using `fallback: true`, however, keeps the integration pod running all the time, which may waste resources.
   
   ### Proposal
   
   Since Kubernetes 1.27, CronJobs support timezone configuration in their spec, so I think we can extract that info from the quartz endpoint and use it to build the CronJob.
   
   ### Open questions

   We can include the parameter in the trait configuration and let the user configure it. I'm about to rework the cron runtime in #5090 so we may have a look at this once that development is over.

   #5090 was dropped in favor of moving the logic directly in the runtime, eventually. I think for the time being this can be developed on Camel K side while the runtimes are not fully available. @lsergio are you planning to work on this by any chance?
