Description

--quorum option introduced for log replication when zookeeper used. Log replication is a great feature.

However, '--quorum' is not very fit into, considering to below:

1. when using with zookeeper, user may confusing with quorum in zookeeper
2. user need to learn how quorum works, why it's necessary.

While use '--num_masters', the user is definitely know how many mesos masters in his/her clusters. It's quite simple and straight-forward.
