Can ValidateBody be made "Generic" from @foal/typestack?

[AleksandrSl]

We have generic entity controller to reduce amount of code and decorators in other controllers and it's very handy to get values for decorators from child controller, e.g. @ValidateBody((controller: EntityController<any>) => controller.paginatedListSchema).
But for ValidateBody @foal/typestack we can't.
Maybe there is a way to add similar lambda based parameter to get class from controller?

Do you want to submit a PR on this? We could probably add some lines in @foal/typestack similar to these ones:

• https://github.com/FoalTS/foal/blob/master/packages/core/src/common/hooks/validate-body.hook.ts#L21
  https://github.com/FoalTS/foal/blob/master/packages/core/src/common/hooks/validate-body.hook.spec.ts#L76
