Add possibility to have more routing keys for one exchange

[Spilky]

This PR is dealing with issue https://github.com/contributte/rabbitmq/issues/59 and add possibility to have more routing keys for one exchange.

Configuration can looks like this:

rabbitmq:
    exchanges:
        testExchange:
            connection: default
            type: direct
            queueBindings:
                testQueue:
                    routingKeys:
                        - key1
                        - key2

But it is still possible to use it like before:

rabbitmq:
    exchanges:
        testExchange:
            connection: default
            type: direct
            queueBindings:
                testQueue:
                    routingKey: key1

Thanks! Do you think it would be possible to do it without a BC break?

@paveljanda look now please. I added new option routingKeys and let routingKey option like it is.

Nice, that's better. Thanks.

Could you add an if clause that would not enable user to set both of those config options? It could prevent some potential bugs.

[Spilky]

@paveljanda I added that if clause here: https://github.com/contributte/rabbitmq/pull/61/files#diff-cc36da72c63c362c7076da3e877940a77546727c17f9b51ad02164553e073281R71. I think that now it is ready to merge and release.

Thanks! Last thing - could you please alter the docs? So that all other people can use it? Thanks a lot! :)
