feat: you can pass dropdown configuration in `forRoot()` method
feat: now you can add dropdown to body by using `container="body"`

BREAKING CHANGES:
- `DropdownModule` renamed to `BsDropdownModule`, same to all dropdown components added `bs` prefix
- `addToggleClass` option is deprecated, now you need to add `dropdown-toggle` class manually if needed
- `dropdownMenu` menu become a template selector, so `*` should be added
sample:  `<ul dropdownMenu>` should become `<ul *dropdownMenu>`
- `onToggle` event deprecated use `isOpenChange` instead
- `appendToBody` deprecated, use `container="body"` instead, now dropdown behaviour and attachment params alligned with tooltips and popovers
- `keyboardNav` deprecated
- `disabled` renamed to `isDisabled`
- `dropdownToggle` doesn't prevent default behaviour anymore
