Related issue to update the list to match the designs: Compliance Framework – Update settings (#371013 - closed)

1. Update the GraphQL query to also fetch the default status of each framework.
2. Add a mutation to the list view to set the default attribute of a framework.
   • Note: Setting one framework to default: true sets all others to default: false. This is worth considering if there's any caching. Ie we mutate one framework to default: true but the previous default framework also shows as default.
3. Add an ellipses icon in a GlButton to the end of the actions.
4. Move the delete action to the ellipses dropdown.
   • Note: Default frameworks cannot be deleted.
5. Add an action for marking the framework as default when not default.
6. Add an action for removing the default status of a framework when it is default.
7. Update list_item.vue to display a GlBadge when the item is default.
8. Update specs.
9. Update documentation https://docs.gitlab.com/ee/user/group/manage.html#compliance-frameworks
