Phalcon\Validation\Validator\Url improvement

[scrnjakovic]

I think this validator should accept flags.

Flag	Used with	Description
FILTER_FLAG_SCHEME_REQUIRED	FILTER_VALIDATE_URL	Requires the URL to contain a scheme part. deprecated
FILTER_FLAG_HOST_REQUIRED	FILTER_VALIDATE_URL	Requires the URL to contain a host part. deprecated
FILTER_FLAG_PATH_REQUIRED	FILTER_VALIDATE_URL	Requires the URL to contain a path part.
FILTER_FLAG_QUERY_REQUIRED	FILTER_VALIDATE_URL	Requires the URL to contain a query string.

$url->addValidator(
    new Url(
        [
            'flags' => [
                'FILTER_FLAG_PATH_REQUIRED'
        ]
    )
);

Actually given that those two flags had no effect since 5.x.x maybe we should consider custom URL validator because filter_var sucks. We need more control, like whether or not to consider protocol for an example. Or simply ditch Url altogether and use Regex...
