DNS records for additional local IP addresses

##### ISSUE TYPE
* Feature Idea

##### COMPONENT NAME
* DNS

##### CLOUDSTACK VERSION
/

##### CONFIGURATION
* for customer isolated network

##### OS / ENVIRONMENT
/

##### SUMMARY
For adaptive computing it's important to get use of additional application local IP addresses which you can move between machines in case of a failure of one of the virtual machines or for upgrades.

I can attach an additional IP to a VM using ACS. But I cannot give that a separate name which does not belong to the actual hostname of the VM.

##### STEPS TO REPRODUCE

##### EXPECTED RESULTS
* possibility to add a DNS name for the additional local IP address
* possibility to move an IP from one system to another (no delete and recreate - IP could be taken in the steps between)

##### ACTUAL RESULTS
* currently the additional IP resolves into the same name as the original IP which is the hostname

CloudStack DNS コンポーネントから始め、追加のローカル IP アドレスが現在どのように VM のホスト名に解決されるかを追跡します。個別の DNS 名を割り当てる方法と、削除して再作成することなく IP を仮想マシン間で移動する方法を定義します。分離された顧客ネットワークで両方の期待される結果が機能すれば完了です。
