[ONOS-4424] Tag LLDP/BDDP source address with fingerprint

Link probes incorporate cluster fingerprint in source
MAC address. This removes the need for an additional TLV and the
complexity associated with it, and also adds fingerprinting to
BDDPs for free.

 - fingerprint in Ethernet source address. The old default MAC
   value is only used when the CusterMetadata service isn't ready.
 - remove support for TLV fingerprint field and associated config
   knobs.
 - links at control domain boundary are classified as EDGE type links.
