Pierre Souchay 251156eb68 Added SOA configuration for DNS settings. (#4714) 
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```
dig +multiline @localhost -p 8600 service.consul

Consul Website

This subdirectory contains the entire source for the Consul Website. This is a Middleman project, which builds a static site from these source files.

Contributions Welcome!

If you find a typo or you feel like you can improve the HTML, CSS, or JavaScript, we welcome contributions. Feel free to open issues or pull requests like any normal GitHub project, and we'll merge it in.

Running the Site Locally

Running the site locally is simple. Clone this repo and run make website.

Then open up http://localhost:4567. Note that some URLs you may need to append ".html" to make them work (in the navigation).
