Allow MessageDecorator to access Process Instance information

[TasosPoim]

Description

It is needed in some cases to propagate headers from incoming Kafka messages that trigger a process instance to Outgoing Kafka Messages ( for example an Authorization Header )

Implementation ideas

@fjtirado suggested that a good place to access the headers is via the MessageDecorator. This could be achieved via accessing the KogitoProcessInstance ( perhaps via injection ) in this interface and use the method getHeaders
