TimerTrigger annotation doesn't cover 'useMonitor' and 'runOnStartup'

I'd like to enable runOnStartup in function.json, but as far as I see the TimerTrigger anntation class, it's not supported.
Additionally, I found that we cannot change useMonitor into false via TimerTrigger anntation.
Should we support these settings in the anotation?

Start with src/main/java/com/microsoft/azure/functions/annotation/TimerTrigger.java and compare its attributes with the timer binding configuration in the linked Azure documentation. Done means the annotation supports runOnStartup and allows useMonitor to be set to false, matching the corresponding function.json settings.
