Consider changing rawBody to be the bytes

[benmccann]

Describe the problem

rawBody sounds to me like its the bytes. Sometimes we put bytes in there and sometimes we put text in there depending on the content type. The biggest issue with this in my mind is that we're making each adapter responsible for that logic, but I think it could live in kit

Describe the proposed solution

Move body parsing from the adapter to kit

Alternatives considered

status quo
