I think we have to add some filter for validating request methods

[Abdujabbar]

In current class:
namespace Atom\Http\Message\Request;
I have seen that in __construct class can receive any string, and we can also just create a class like this:
$request = new Request('any_string');
but this is wrong in my opinion, maybe we will create some array for validating this.

protected $availableMethods = ['get', 'post', 'options' ...]

and than check is method in current array in
filterMethod($method)

What do think about this?

I think these abilities needed for performing own methods, like ANY and etc.. methods, even if they are not described in the RFC specifications.
