That merges up cleanly all the way to trunk.  Adds a -D option to disable using severity in
DynamicEndpointSnitch calculations.

> I have seen in a few clusters now where severity can out weigh latency in DynamicEndpointSnitch
causing issues (a node that is completely overloaded CPU wise and has super high latency will
get selected for queries, even though nodes with much lower latency exist, but they have a
higher severity score).  There should be a way to disable the use of severity.
