Zookeeper 1748: Add option for tcp keepalive
As referenced in https://issues.apache.org/jira/browse/ZOOKEEPER-1748 and
https://github.com/apache/zookeeper/pull/83, add the option to use keepalived
on quorum connections. These connections are often idle and long-lived, thus
tend to be silently dropped by intermediate networking infrastructure (AWS
Security Groups' state tables, for example).
This PR adds the option to use the system's keepalive functionality when
creating the socket for quorum connections.
It does not change existing behavior.
