Supported formats are different from the Swagger spec

[honzajavorek]

See apiaryio/dredd#681. TL;DR Swagger spec supports a different set of formats then JSON Schema spec. The adapter (to be more precise the JSON Schema faker in the adapter) follows the JSON Schema spec. We should support Swagger spec in the first place though.

        "website": {
          "type": "string",
          "format": "url"
        }

We need to list all the different formats swagger spec supports.

http://swagger.io/specification/#data-types-12 has a list of all the formats and we can use https://github.com/json-schema-faker/json-schema-faker#custom-formats to add custom format for these types.
