[Feature Request] details row to accept widgets by default

[pxpm]

Feature Request

What's the feature you think Backpack should have?

I got this request/idea from a discussion in Laravel-Backpack/community-forum#712 where @susanu shared some code he's using in his project.

Basically the idea is to replace the empty details row blade template with a template that outputs widgets you can configure in your crud panels.

Have you already implemented a prototype solution, for your own project?

@susanu did implemented a prototype, it's in the linked discussion.

Do you see this as a core feature or an add-on?

I think we could do this change as a NON-BC in core.
