Title: Hook CMB later - ensure normal init hooks are done

Use case:

I wanted to programatically create CMB fields based on taxonomy/term data. However - with CMB in MU plugins, this was getting hooked in before the taxonomies were registered.

I think it makes sense to fire this later - to ensure that all normal init stuff has been run before this.
