How to set the AppScheduler misfire_grace_time parameter in stackstorm ?

[lemeur]

On one stackstorm installation I've got missing CronTimer events.

In the log I get these kind of entries:
stackstorm st2timersengine[27662]: 2022-11-27 20:45:02,381 WARNING [-] Run time of job "St2Timer._emit_trigger_instance (trigger: cron[hour='20', minute='45'], next run at: 2022-11-28 20:45:00 UTC)" was missed by 0:00:02.381851

After a little Googling, I think I need to set the misfire_grace_time parameter of the AppScheduler component used by Stackstorm.

Howerver I see no such option in the timersengine section of st2.conf, nor in the rule definition for the core.st2.CronTimer trigger.

Can someone point me to the correct way to set this parameter ?

Here are the details of the technical environnement:
==> The server is installed on a Virtual Machine, which may explain why it is possible, under a high load on the hypervisor, that the VM misses "clock ticks".

This is the same issue as #5831

For now, just scheduling the task at a different time has solved the issue. this is clearly related to some VM-Host load.
However my sysadmin hasn't seen any CPU-Wait warning, there might be some I/O wait because the error occurred during the VM-backup window.
