MSTP update - 7: added MSTP bridge port extended parameters

Added #bridge #port #extended #configuration #parameter s in MSTP module. These include parameters like #AUTO_EDGE, #AUTO_ISOLATE, etc ... This will transition the port to edge mode when not receiving BPDU s. Also isolates the point-to-point link when BPDU s are not received from the peer bridge on it anymore.
