Title: Improve use of job start and end events in spring

 
User Story (Required on creation):
As a developer i would like to provide the "business team" the possibility to cover e.g. the authentication at the beginning /end of an asynchronous job, so they can focus on the business logic.
 

Functional Requirements (Required before implementation):
I can currently use a CommandInterceptor to execute code (E.g. logging, system authentication) at the process starts and ends for a Camunda Engine embedded in a Spring Boot application.
Sending an Event JobStarted and JobFinished to the Spring Eventing Bridge, without plugins and interceptors, would be a more easily understandable implementation.
 

Limitations of Scope (Optional):
