> Copied from HORNETQ-1270
> The DNS SRV record provides a convenient and well known mechanism to configure active-active, load balanced clusters and to provide failover information.
> It is convenient for many people because they already have DNS servers and support staff are usually familiar with the procedures for maintaining the DNS entries.
> DNS SRV also allows port numbers to be advertised.
> The clustering support using UDP multicast doesn't work for all sites, especially where the user is more concerned with failover than load-balancing.
> A specific DNS SRV implementation may involve some or all of the following:
> - clients discovering a HornetQ, JNDI or STOMP host and port
> - servers dynamically deciding which IPs and ports to bind to by checking DNS SRV records
> - servers dynamically deciding which other servers to cluster with by checking for DNS SRV records
> DNS SRV records may look like this:
> _stomp._tcp.test-mq.example.org. IN SRV 1 50 5566 testmqhost1.example.org.
> _stomp._tcp.test-mq.example.org. IN SRV 2 50 5566 testmqbackup.example.org.
> A STOMP client would then be configured with just the domain name "test-mq.example.org" and it would dynamically discover the hosts and ports from DNS
