Add SoftLayer DNS provider (#59)

Add SoftLayer DNS as a DomainServiceProvider.

The SoftLayer API is a bit of a mess and treats MX and SRV records
differently. This leads to some replication and custom handling issues
to work around.

In this patch I have to change the SRV test case to be _tcp instead of
_protocol because softlayer requires a "known" protocol which AFAICT is
tcp, udp or tls. I think this will be acceptable in most cases.

# SoftLayer DNS Provider
## Configuration
To authenticate with softlayer requires at least a `username` and `api_key` for authentication.
It can also optionally take a `timeout` and `endpoint_url` parameter however these are optional and will use standard defaults if not provided.
These can be supplied via the standard 'creds.json' like so:
{% highlight json %}
"softlayer": {
"username": "myusername",
"api_key": "mysecretapikey"
}
{% endhighlight %}
To maintain compatibility with existing softlayer CLI services these can also be provided by the `SL_USERNAME` and `SL_API_KEY` environment variables or specified in the ~/.softlayer.
More information about these methods can be found at [the softlayer-go library documentation](https://github.com/softlayer/softlayer-go#sessions).
## Usage
Use this provider like any other DNS Provider:
{% highlight js %}
var registrar = NewRegistrar("none","NONE"); // no registrar
var softlayer = NewDnsProvider("softlayer", "SOFTLAYER");
D("example.tld", registrary, DnsProvider(softlayer),
A("test","1.2.3.4")
);
{%endhighlight%}
## Metadata
This provider does not recognize any special metadata fields unique to SoftLayer dns.
For compatibility with the pre-generated NAMESERVER fields it's recommended to set the NS TTL to 86400 such as:
{% highlight js %}
D("example.tld", registrary, DnsProvider(softlayer),
{"ns_ttl": "86400"},
A("test","1.2.3.4")
);
{%endhighlight%}
`ns_ttl` is a standard metadata field that applies to all providers.
