The Bootstrap carousel module is used for image carousels, and we don't
use it anywhere on the site. Also separated the Bootstrap JavaScript into separate components and removed the carousel component.
Fixes#14670.
Decouple membership and notifications
This allow you to have notification setting per project even if you are member of group.
It also creates background for having notification settings in project you are not member of.

For #3359
After this merge request there is still some work to be done:
* create migration that remove duplicates in notification settings table and create uniq index (8.8 probably)
* remove notification_level field from Member model in 9.0
* make proper API for notification settings
* use `MemberCreateService` instead of Member#after_create callback for creating notification settings (after #14709)
* maybe more tests
