Update sync scheduler (#1297)
* Add `stop()` methods to shutdown to shutdown procedure

why:
  Nasty behaviour when hitting Ctrl-C, otherwise

* Add background service to sync scheduler

why:
  The background service will be used for sync data import and recovery
  after restart.

   It is controlled by the sync scheduler for an easy turn/on off API.

also:
  Simplified snap ticker time calc.

* Fix typo
