BindDnsServer really supports Ubuntu and Debian

As the title says, the BindDnsServer entity should work on Debian and Ubuntu machines.  It has been tested on CentOS 6.3, Ubuntu 14.04 and Debian 7.6 VMs. I've also made general improvements to robustness and integration tests.

The easiest way to test is to run Maven with `-PLive -Dtest=BindDnsServerByonLiveTest -DlocationSpec='<a byon spec>'`.

It is worth reviewing the RFC1912 configuration (`rfc1912.zone`) and the three additional zone files: `named.localhost`, `named.loopback` and `named.empty`.
