Breaking Changes

General: Fix serialization of data in HTTP

There is a new serializer in place to automatically detect the Content-Type for the data when using the HTTP Protocol and serialize accordingly. Objects will be send as application/json, Cloud-Events as applications/cloudevents+json, Strings as text/plain, and others as application/octet-stream.

An example of this change can be seen when performing client.invoke with "hello world" as data. The new serializer will correctly return the string type, as opposed to the previous behavior of calling JSON.serialize and returning '"hello world"'.

PubSub: Changes to the subscribe callback for HTTP

The HTTP subscribe callback now returns data after parsing it correctly. Data is either extracted from the body's data field, or the data_base64 field. data_base64 is always expected to be a base64 encoded string, and will be decoded and parsed as JSON if possible. If it is not JSON, it will be returned as a string. If data is not found in either field, the entire body will be returned as-is.
