Add cron trigger table (#14110)

This Pr begins the extensibility journey
- adds a `core.cronTrigger` table
- add a oneToMany relation between core.serverlessFunction and
`core.cronTrigger` (one serverlessFunction can be triggered by multiple
cronTriggers)
- add a job to trigger a serverless function
- adds a cron to trigger serverlessFunction (via the trigger job) based
on the core.cronTrigger.setting.pattern
- adds a command to register the cron
- add the command in `cron-register-all.command.ts`
