This is primarily related to Cloud Events. Since we delegate to a separate class for post processing, if outpt message is Cloud Event we will not be doing anything to with regard to header copy in SimpleFunctionRegistry and unstead delegate it to CloudEventFunctionInvocationHelper
This commit effectively a merge of work with #607 and simplifies the following
- CloudEventAttributesProvider now provides CloudEventAttributes initialized with defaults to be set by the user
- In HTTP RequestProcessor the logic of sanitizing headers was improved to ensure that correct prefix is applied
Resolves#607
Normalizing in this context means converting it to binary-mode so the rest of the processing logic is the same.
Added support for canonical attribute names. Now, internally any attribute can be set as 'ce_' regardless where it came from are where it goes to as the frameork will be able to recognize both
Removed CloudEventMessageConverter
Renamed CloudEventAttributes to CloudEventAttributesHelperas it is better suited to what it actually does
