Rework to the DHCP analyzer.

Browse source 
Highlights:
 - Reduced all DHCP events into a single dhcp_message event. (removed legacy events since they weren't widely used anyway)
 - Support many more DHCP options.
 - DHCP log is completely reworked and now represents DHCP sessions
   based on the transaction ID (and works on clusters).
 - Removed the known-devices-and-hostnames script since it's generally
   less relevant now with the updated log.
