add a special case for default url format validation

[KeranChen]

Environment

• Ember Version: 2.18.2
• Ember CLI Version:2.15.1
• Ember CP Validations Version:4.0.0-beta.1

Steps to Reproduce

The default format validator for url will return false for the shortened urls from our company's tiny url generator. (eg. http://bburl/abcd), so I want to add a special case to the default url format validator. I wonder whether you could add that special case to the default url format validator? After I upgrade the ember-cp-validations to 4.0.0-beta.1, I find a working solution, which is to create a customized validator.

export default BaseValidator.extend({
    validate(value) {
        const result = this.test('format', value, {
            type: 'url',
            allowBlank: true
        });
        const bburl = /^(https?:\/\/bburl)/;
        if (result.isValid || bburl.test(value)) {
            return true;
        } else {
            return 'Has to be in a valid URL format';
        }
    }
});

I wonder whether you could make the change on your side, if not, what is your suggestion on this issue? Thank you!

Would it be possible to expand the regex to include urls that don't have top level domains? I don't think that is required for a url to be valid.
