I really like the idea to replace real sensors in Quick-Dev with data
generators; aka spouts that spit-out canned data.  The pcap replay
mechanism is fairly resource intensive, not to mention all of the sensors
like Bro, Snort, etc.  Removing these should give us significantly more
head room.

At the same time, it is going to be useful in some cases to have a single
node that can run end-to-end with sensors.  For example, I still want to
have a box that I can drop in different pcap files and capture telemetry
for testing.  I think we should continue to maintain Full-Dev with the
current sensor suite.

In addition, having these data generators can help with performance
testing, if we add the right toggles and switches.  Like the ability to
control the throughput, etc.
