Adding prepareForValidation method

[nfunwigabga]

I wonder if it would be useful to have a prepareForValidation method, as we currently have in FormRequest. This would be useful if we want to do some transformation on the request before validating and setting it in the Data class.

Hi @nfunwigabga,

This looks like a good idea, I would accept a documented and tested PR with this feature!

Hi @rubenvanassche

where is the documentation for modifying properties before the data pipeline?

I don't see it on the documentation pages

I made a PR 277 for the missing documentation.

Looks like the docs site isn't working as it should:

laravel-data/docs/advanced-usage/pipeline.md

Line 67 in 8b4d79b

Sometimes you need to make some changes to the payload after it has been normalized, but before they are sent into the data pipeline. You can do this using the `prepareForPipeline` method as follows:

Manual regenerate fixed the problem!
