Schemas containing circular references are ignored

[Michael Su]

When a schema that contains a circular reference is encountered that schema is ignored during validation. This means the mock examples of the schema are not validated.

For example:

"definitions": {
    "Content": {
        "type": "object",
        "properties": {
            "ancestors": {
                "type": "array",
                "items": {
                    "$ref": "#/definitions/Content"
                }
            }
    }
}

feat: add support for circular references in the swagger file

Close #60

BREAKING CHANGE:

swagger-mock-validator now supports validating schemas containing circular references. Prior to this change schemas containing circular references were ignored. If you have a schema that contains circular references and a mock that is not compatible with that schema the swagger-mock-validator will now fail.

It is recommended that consumers and providers coordinate upgrading to this release so that both sides agree on what is considered valid vs invalid.
