DPP2: Presence Announcement processing in AP/Relay

Browse source 
Process the received Presence Announcement frames in AP/Relay. If a
matching bootstrapping entry for the peer is found in a local
Configurator, that Configurator is used. Otherwise, the frame is relayed
to the first configured Controller (if available).
