vBucket Aware client accepts only 1 server

The vBucket Aware client only accepts 1 server. So if that server is down at the time of initial connection. The client will never connect. This results in users needing to write special code to handle this or put a Load Balance in between. Which a balancer would reduce performance. Client should ideally take a collection of servers like Standard Memcached Clients do, and auto connect to a different one if it fails connection.
