Quarkus-Quartz: Jobs running concurrently in clustered environment

Describe the bug Hi,

I was using Quarkus/Quartz in my project to manage jobs in a clustered environment. My requirement is that the my job is running exactly once.

Following this guide: https://quarkus.io/guides/scheduler-reference#concurrent_execution my Job method looked like this:

@Scheduled(every = "15s", concurrentExecution = SKIP) 
void nonConcurrent() throws Exception {
  logger.info("start");
  Thread.sleep(30000);
  logger.info("end");
}

Running locally, the job was really just executed once. In my cluster, the job was executed exactly once by each pod.

Expected behavior I expected concurrentExecution = SKIP to make use of the Job configuration parameter is_nonconcurrent which is used by quartz to ensure a job is running nonconcurrently.

Actual behavior is_nonconcurrent is not set by concurrentExecution = SKIP. Jobs are actually executed concurrently in a multi-pod environment

To Reproduce

Steps to reproduce the behavior:

1. Setup project with quarkus and quartz
2. Create the job mentioned above
3. Run multiple pods

Configuration Quarkus version: 1.10.5.Final

quarkus:
    quartz:
      clustered: true
      store-type: jdbc_cmt
