Vinod Mangalpally 67cc68e903 mdns: Add support for NOTIFY's
designate-mdns will be notified by Central when changes are made
to a zone. The service will issue a NOTIFY to all slave nameservers.

Currently this is a pre-configured list of slaves to NOTIFY.  After
Pools, the list of slaves to NOTIFY will be loaded dynamically.

Change-Id: Iead2287f79726eddbb225538de961332cda49f24
Implements: blueprint mdns-designate-mdns-notify
