Fixing serialization problems with ObjectNormalizer + more helpers

[weaverryan]

The TransportConfiguration is currently broken for default Messenger installs because the default install uses the ObjectNormalizer for serialization, which causes several problems:

• The required constructor makes it not serializable
• Some of the incorrect phpdoc above the properties also caused it to fail

I've re-worked this class to play nicely with the ObjectNormalizer. AND, I've added methods for the most common options/methods that you'll want to configure on your message. This makes the experience a bit nicer, while still making the old way work

// before (still works)
$envelope = (new Envelope($message))
    ->with(new TransportConfiguration(['metadata' => [
        'deliveryDelay' => 10000
    ]]))
;

// after
$envelope = (new Envelope($message))
    ->with((new TransportConfiguration())->setDeliveryDelay(10000))
;

Thanks!

Seems like a nice addition to the project but looks like its more aimed at AMQP then the generic Message.

Yea, I was trying to list some of the most common "options" that you would need. But some won't be supported by your specific transport, and there may be other options that are on your Message class that we don't have helper methods for here (but you can still add it via metadata). It's kind of an imperfect "cover the most common cases" attempt. Fortunately, the error is quite good if you try to set any metadata but your Message class does not have a corresponding setter method for that.

Thanks, @weaverryan. Shall we get this merged?
