Don't automatically parse input to JSON when using invoke and invoke local

[pmuens]

This is a Feature Proposal

Description

Currently we're assuming that the input for the invoke and invoke local command is a string which can be parsed (and will be parsed) into JSON.

However some AWS services assume other inputs.

We should update the invoke and invoke local command to reflect that (see: #2833 (comment) and #2833 (comment)).

Thanks @wxs and @dzimine for bringing this up 👍

Please take a look at the PR #4036 and see if you're ok with:

1. parsing by default - my reason is "not break current user's experience", someone may be using it already.
2. --raw - happy to take a better suggestion

Great! Thanks for taking a stab at it @dzimine 🎉. The implementation sounds reasonable 👍.

We'll look into it ASAP!
