Periodic Events

[soccermax]

fix #14

• add new eventType: periodic events
• periodicity should be defined every X seconds in yaml
• during startup check persistence and schedule jobs
• during selection - check that there is always one open entry
• period jobs should have no status
• check that there are no duplicated event type registrations
• check period event registrations --> much less parameters
• validations period not too small
• also add event registration parameters for normal events
• handle onboardings
• do an extra run to schedule again for next processing - or maybe direclty during publish
• test what happens if run is longer than interval
• periodicEventOffset is currently not used anymore - delete?
• publish should not allow periodic events

handle next:

• variable to skip run if already running
• periodic without tenant context (maybe do in next iteration)
• add info to documentation
• what is with load - rework complete load parameter for ad-hoc redis events and so on
• allow duplicate usage if ad hoc and periodic
• parameter to deactivate periodic event runner (for e.g. local use cases)
• how to handle longer downtime (deployment)
• lock is still blocked if tick is overdue
