SSL proxy for API endpoints

This will enable https on both the regular (port 5000) and admin (port 35357) API endpoints and use mod_proxy to point to the http native api. For now this relies on both of the other endpoints to listen on localhost only so there is no port conflict. I didn't include an attribute to set that in here but it would be good to have feedback on that.

I did some basic testing using curl using the following command. You can test it locally inside of the vm by pointing to the local ip for it:

``` bash
curl -i --insecure -H "Content-Type: application/json"  -d '           
{ "auth": {
    "identity": {
      "methods": ["password"],
      "password": {
        "user": {
          "name": "admin",
          "domain": { "id": "default" },
          "password": "admin"
        }
      }
    }
  }                                           
}' https://<ip address>:5000/v3/auth/tokens
```

I haven't tested this on a full cluster to see whether or not there are bad problems with the various services talking SSL. I imagine there will be an issue with that. One way to work around it is to use a virtual ip for the https and keep the regular port http but lock it down via a firewall rule.

It's also debatable whether or not to make this feature optional on some clusters and whether or not I should move this code to its own recipe (probably an underscore recipe).

Anyways, this is a work in progress and can use some input from others.
