Encrypt the CloudEvent "data" attribute

On today’s call Tam asked if we wanted to add the ability to encrypt the CloudEvent’s data attribute to ensure it is not tampered with. Please add your thoughts on this topic to this issue so we can have a record of the discussion.

In the end, we’ll either add a new feature to the spec or we’ll add something to the Primer explaining why we chose to do nothing so that new folks can understand our reasoning behind the decision since this questions has come up more than once in the past.

@JemDay in your first point, is there a typo? did you mean to say “SHOULD NOT” ?

When the data field is encrypted, I’m assuming you just set datacontenttype to be multipart/encrypted? Any example of that in the wild?
