Current behavior

Cannot set runOnInit by Cron decorator
https://github.com/nestjs/schedule/blob/master/lib/decorators/cron.decorator.ts#L22

Expected behavior

Can set runOnInit by Cron decorator.
I think you can use runOnInit options instead of starting cron on application bootstrap
https://github.com/nestjs/schedule/blob/master/lib/scheduler.orchestrator.ts#L81

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

You can decide to run a cron at startup or not. I know you can use "Dynamic Cron jobs" but I think using decorators is a better way.
