    Support sending dynamic DNS updates.
    
    DocImpact: there is a new DNS update driver, which supports sending
    dynamic DNS updates to DNS servers that support such things, for
    example bind.
    
    Configuring this in my test environment required setting the following
    flag values:
    
    instance_dns_manager = nova.network.dyndns.DynamicDNS
    instance_dns_domain = dyn.example.com
    dynamic_dns_domains = dyn.example.com
    dynamic_dns_server = 192.168.1.20
    dynamic_dns_key_name = test
    dynamic_dns_secret = Wr1784mFhyTP9nqXIkWpRw==
    
    You also need to configure the domain with the nova client:
    
    nova dns-create-private-domain dyn.example.com
