  - 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.
