Improved Content Type Resolution

The content-type resolution has been improved and consolidated in the channel interceptors, which makes it configurable for situations that require application-level customizations. Also, based on the community feedback, we now set the default content-type as application/json. However, it is still possible to override it via BindingProperties or it can be passed with the Message coming from an upstream application.
