[FEATURE] show raw input/response within tasks

Is your feature request related to a problem? Please describe.
I was experiencing some uncertainty when making calls to my expensive GPT4 model w.r.t. the actual prompts I was sending to it. You might want to disable this for memory purposes but I think it would be good to have the formatted prompts available or accessible somewhere during pipeline/project iteration.

Describe the solution you'd like
An optional flag to show raw_output and/or raw_input

Describe alternatives you've considered
N.A.

Additional context

There is an add_raw_output flag that since 1.2.0 is going to have a default value of True. This will add a raw_output in the distilabel_metadata dictionary.

For the raw_input, we can do the same, add a add_raw_input flag.
