Description of problem:
Currently, the MiqEventHandler and MiqScheduleWorker memory threshold settings are not exposed in the UI. This forces customer to have to manually edit the 'Advanced Settings' tab in order to adjust these worker settings. Several consulting engagements recently have revealed these workers exceeding memory limitations and require a manual adjustment. It is both A) not ideal, and B) not consistent to have to adjust these 2 worker setting via the 'Advanced Settings' tab.
Currently, the workaround is to do this in the Advanced Settings for each worker:
:memory_threshold: 250.megabytes <<< adjust the MiqScheudleWorker memory threshold
:memory_threshold: 800.megabytes <<< adjust the MiqEventHandler memory threshold
The above should be rolled into the UI when selecting Configuration > Zones > ZONE_NAME > Servers > SERVER_NAME > Workers, as this is where the rest of the worker memory threshold settings are adjusted. This would make the process both consistent and much more clear.
