Steps to reproduce:
1) create a process application, whereby ProcessApplicationInterface#getExecutionListeners() returns at least one global process application execution listener
2) start a process instance
3) complete the process instance (or cancel the process instance)

Problem:

• The returned global process application execution listener is not invoked on process instance start.
• The returned global process application execution listener is not invoked on process instance end.

Hint:
The ProcessApplicationEventListenerDelegate is not added as start and end listener for the process, see https://github.com/camunda/camunda-bpm-platform/blob/master/engine/src/main/java/org/camunda/bpm/application/impl/event/ProcessApplicationEventParseListener.java#L69-L71
