cluster_backend_zeromq: Set Cluster::Backend::ZeroMQ::ipv6=T when needed#101

Conversation
Now that Cluster::Backend::ZeroMQ::ipv6 defaults to false, ensure it is toggled to true if any of the node addresses resolves to an IPv6 address. Also, add brackets around IPv6 addresses for the ZeroMQ endpoints as otherwise ZeroMQ will consider the addresses as a device. Add a test for this, too. Relates to #5251
