Add passthrough properties for APEX engine

APEX event receiver and sender plugins sometimes need to exchange
information with tasks, especially in the case of REST communication.
This change enables passthrough of Properties from the event carrier
technology plugins to APEX task, task selection, and state finalizer
logics.

Apologies for the size of the review but this change involves passinng
the properties through all the APEX components, hence the large number
of small changes.
