Add parameter to lifecycleParticipant

Following on #422 

It adds the ability to use parameters in the pom to customize the way the lifecycleParticipant deals with dependencies in the libs folder of the apklib/aar

This is now complete.
Do we really want to make a Helper class for something that will only be used in a LifecycleParticipant? I don't think we'll have another Participant and if we do we might want to extract that at that moment no?
