Pass Path as an argument to hooks, validate, defaultValue, filterOptions(for relations) etc.

Description

Sometimes for deep structured documents, even with depth 2, like group->group, array->array, it is required to get context of outer array Item, or group fields, but there is no way for that. We have though access to data of a document, but we also need a path to:

• Get to the outer array item, because its name ( index ) is dynamic.
• In case of Group Fields to write reusable Field Schemas

This request concerns fieldHooks, validations, defaultValue, filterOptions etc.

Golden idea.

Gonna add this to our roadmap. I think it's a great addition.
