Add a possibility to bypass requests to another request method without a redirect

[hollodotme]

When state changing requests hit the server via GET request method, we need to handle them (and change state) on the read side. This breaks the approach of separating read / write by their meanings.

In order to handle such a state changing GET request correctly, add configurable request bypasses to internally reroute the read request to a write request, so that a write request handler is responsible for handling the request and the business logic is kept separated.

<?php declare(strict_types=1);

namespace YourVendor\YourProject;

class IceHawkConfig implements ConfiguresIceHawk
{
    public function getRequestBypasses()
    {
        return [
            new RequestBypass( 
                new Literal('/get/that/writes'), 
                '/write/that/handles', 
                HttpMethod::POST 
            ),
        ];
    }
}

The bypasser will - if necessary - create a new request info object that is matched against the normal routing definitions.
