Implement option for ignoring is_uploaded_file check in File validator

[FaimMedia]

The AbstractFile class has the method checkIsUploadedFile. However if I want to mock/fake an uploaded file for in example unit testing, I have implement/override all these classes, since they all extend from it:

• Phalcon\Filter\Validation\Validator\File\Resolution\Min
• Phalcon\Filter\Validation\Validator\File\Resolution\Max
• Phalcon\Filter\Validation\Validator\File\Resolution\Equal
• Phalcon\Filter\Validation\Validator\File\Size\Min
• Phalcon\Filter\Validation\Validator\File\Size\Max
• Phalcon\Filter\Validation\Validator\File\Size\Equal
• Phalcon\Filter\Validation\Validator\File\MimeType
• Phalcon\Filter\Validation\Validator\File

cphalcon/phalcon/Filter/Validation/Validator/File/AbstractFile.zep

Lines 381 to 392 in 83677f1

	/**
	* Checks if a file has been uploaded; Internal check that can be
	* overridden in a subclass if you do not want to check uploaded files
	*
	* @param string $name
	*
	* @return bool
	*/
	protected function checkIsUploadedFile(string name) -> bool
	{
	return is_uploaded_file(name);
	}

Would be much easier if an option would be implemented like:

    protected function checkIsUploadedFile(string name) -> bool
    {
         if ($this->getOption('ignoreCheckUploadedFile')) {
            return true;
        }

        return is_uploaded_file(name);
    }

As an addition, it would also be nice if this validator accepted the Phalcon native $this->request->getUploadedFiles() instead of the PHP's $_FILES.
