reed@google.com fb2cd425c2 add --exclude-config to opt out of 1 or more configs. This always is respected, 
regardless of the ordering of --config and --exclude-config.

add --verbose [-v] to dump extra info, e.g. what configs are being run

changed --config to enforce a unique set of configs to be run, such that
--config 8888 --config 8888 results in just 1 run of 8888.
