Bug Description

When tooz is configured to use zookeeper, the membership list reported by the library always includes an additional 'leader' member. When using the member list to create the hash table, we end up with a partition in the table for a member that doesn't actually exist. We should account for this zookeeper-ism and just ignore that member.

    Filter the 'leader' member from cluster membership list

    When configured to use zookeeper, tooz reports an additional member
    named 'leader' in its membership list. This can mess with construction
    of the hash table. This removes it from the list of members we use for
    the DHT.
