LACP upgrade - 1: updated LACP aggregator and member port activation handler

Updated the port status #activation #handler for both #aggregator and the #member-port in #LACP module. The data type references has been corrected to use the new updated type. The activation handlers #cascade the #configuration #state #changes from the #LAG module to LACP module. On moving the port to #active state from LAG module, the #LACP #protocol specific procedures will be #started for these ports. Similarly on putting these ports in to #not-in-service or #not-ready state, the #protocol procedures are #stopped and #cleanup is done for these ports.

LAG upgrade - 22: updating aggregator activation handler

Updating the #aggregator #activation handler in LAG module. The references to the augmented aggregator data-structures has been updated to the standard aggregator data-structures. This allows to directly use the #standard #aggregator data-structure and use the #embedded custom aggregator data-structure for internal operations. The #status related parameters are kept in the custom data-structure and on aggregator status #change these are updated as #active / #not-in-service. When aggregator are not ready to participate in the normal operations because of inconsistency in the applied configuration the state is set as #not-ready.
