Add scheduler subsystem

Description

SiteWhere does not have the concept of scheduling actions to happen at a future time or at a recurring time/interval. The feature can be applied for many different aspects of the system including command invocations, batch operations, cleanup operations, etc. The implementation should account for:

  • Cron-style scheduling expressions

  • Scheduling tasks on an interval

  • Scheduling tasks for one-time fire in the future

  • Persistence of schedules in the datastore

  • User interface for defining schedules

  • Updates to allow command invocations to be scheduled
