Description

The beta-update start currently relies on a scheduler-driven message, which suggests the use of an API that does not have a correspondent client command:

aurora2 beta-update start  devcluster/vagrant/test/cron_hello_world4 aurora/examples/jobs/cron_hello_world.aurora
Failed to start scheduler-driven update due to error:
	Cron jobs may only be updated by calling replaceCronTemplate.
Error executing command: Failed to start scheduler-driven update due to error:

Need to fail fast the "aurora beta-update start" for a cron job config.
