multiCheckbox with a key in a nested json model does not work

[kranthitech]

Noticed an error with multi select.

If the key is of the form "model", it works fine and the model is bound to an array based on the selected checkboxes
But when key is of the form "model.something", it gets bound to a boolean instead of an array, and all the checkboxes get selected or de-selected at once.

Hi @kentcdodds , I have tried to reproduce the same issue.

Ah, yeah, here's the problem:

1. When you provide a key that's nested this code runs to replace any instance of ng-model in the template with 'model.' + options.key.
2. With this template the ng-model needs to actually remain the same.

So I suggest that we add a value in extras of fields to disable/control (via a function) the manipulation of nested keys and then utilize that in the defaultOptions of this type.

Note: This will take work in both this repo and the formly core repo.

i resolved this issue on my local enviroment. I had to make some adjustments in formlyCore to accomodate the use case, as well as modifying the multiCheckbox controller.
