[dnsdist] dnsdist NOTIFY distribution to several slaves

[Winfried Angele]

Hello Stefan,

It's a bit of a hack, because not meant for that. But TeeAction 
(https://www.dnsdist.org/rules-actions.html#TeeAction) could work maybe.

Example:

addAction(OpcodeRule(DNSOpcode.Notify),TeeAction("192.168.2.1"))
addAction(OpcodeRule(DNSOpcode.Notify),TeeAction("192.168.2.2"))
addAction(OpcodeRule(DNSOpcode.Notify),TeeAction("192.168.2.3"))
