Refactored reception handler parameter handling
Refactored parameter handling for configuration of reception handlers as the previous implementation does not align with the plugin architecture (.e. plugin specific parameters being handled in core code) Issue-ID: POLICY-1094 Change-Id: I31a9fc7f712ca43f0f69c42a6d99fa481b02cd4b Signed-off-by: mmis <michael.morris@ericsson.com>
