disco/etcd work: fix lots of races, start all cluster nodes at once.

Browse source 
port mapper gives out ports from 63000-65000 for the tests

fix another race

http test uses port.MustGetPort

rbf: remove :0 port request

ocd happy

test fix for grpc listener address already in use

test/disco allocates BindGRPC port from the port mapper

dump stack on each GetPort

verify each port is usable right away

server/config.go has Config.Validate() now

panic if gossip port is 0. validate server.Config

fix another gossip port 0

builds

quiet, don't dump stack on each port alloc

builds

happy linter

even gossip fallback should not be zero but rather use the port mapper
