Install and configure bind with dnssec

## Requirements

 * bind version >= 9.8

## Official support OS

* Debian
  * stretch
  * jessie

This role can work on Debian derived OS, but it's not our priority.

## Role variables

* `bind_role` - the role `master` or `slave`, don't generate dnssec key on `slave`
* `bind_options` - hash general bind options
* `bind_zones` - the dns zones
* `bind_zones_subset` array to use in `extra-vars` with the list zones to update
* `bind_listen_ipv4` - enable or disable ip v4 support (default: true)
* `bind_listen_ipv6` - enable or disable ip v6 support (default: true)

## How to use

* `host_vars/dns-master`
 ```
 bind_role: master
 ```

* `host_vars/dns-slave`
 ```
 bind_role: slave
 ```

* `group_vars/dns-server`
 ```
