Access to rawBody from request.

[glani]

Is your feature request related to a problem? Please describe.

In the current implementation of the trigger context, the body has already been parsed.
However several services make a signature of body based on rawBody request.

for example: "tax_formatted":"\u20ac0.57","discount_total":1199,"total_formatted":"\u20ac3.57",
will be decoded to json:

"tax_formatted": "€0.57",
"discount_total": 1199,
"total_formatted": "€3.57",

as a result, it is impossible to restore the original rawBody.
In the end, the webhook signature is incorrect.

Describe the solution you'd like
context should have access to raw text body in case of json/urlencode-form request

Describe alternatives you've considered
as a workaround I switched off the trigger signaturecheck
