Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15203

One use case for this is manually setting the "action" tag for Grape API
calls. Due to Grape running blocks there are no human readable method
names that can be used for the "action" tag, thus we have to set these
manually on a case by case basis.

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

Wrap text in notes box if longer than code in diff

* Fixes branch name overflow
