At the moment, it is possible to "register" one Codec per contentType via ContentSerdes.

e.g., ContentSerdes.get().addCodec(new MyCodec("application/myType"))

There are situations where this is not enough. For example, one might want to register a generic codec for application/octet-stream and yet another for the same application/octet-stream which is used for binding-opcua only.

We should extend the API in a way to allow for that use-case.
