API: Ability to update a group

This makes it much easier to update a group after introducing the group visibility.

* Closes #14991 

See merge request !3587

To reproduce:

1. Create a project with some content
2. Rename the project
3. Create a new project with the same name.
4. Boom - 404.

After step 2, the branch and tag counts were not being cleared. This would
cause `repository.has_visible_content?` to erroneously return `true`
for the newly-created project.

Closes #13384

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. 


- [x] Make it work
- [x] Migrations
- [x] CHANGELOG
- [x] More tests
- [x] API

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

Add proper nil and error handling to SAML login process

While writing the feature that would allow certain Omniauth providers to be marked as external I noticed that there is a scenario where the `gl_user` method can return `nil` and if this is not properly checked, it will lead to exceptions that will cause 500 errors. It is quite easy to land in this scenario, so I added `nil` checks.

I also noticed that the `saml` method in the `omniauth_callbacks_controller.rb` file lacked a `rescue` for `Gitlab::OAuth::SignupDisabledError`, which can happen if the default configuration from `1_settings.rb` is applied. So I also added this check.

Fix #14753: Check if head is born before trying to detect main language

This MR makes sure that head exists before trying to detect the main language.
This prevents errors on repo's without a master branch.

Closes #14753
