Merge branch '4009-external-users' into 'master'

External Users

The user has the rights of a public user execpt it can never create a project, group, or team. Also it cant view internal projects.

Partially fix for both #4009 and #13938 (except the LDAP sync or a pattern to detect external users)

+## External Users
+
+In cases where it is desired that a user has access only to some internal or
+private projects, there is the option of creating **External Users**. This
+feature may be useful when for example a contractor is working on a given
+project and should only have access to that project.
+
+External users can only access projects to which they are explicitly granted
+access, thus hiding all other internal or private ones from them. Access can be
+granted by adding the user as member to the project or group.
+
+They will, like usual users, receive a role in the project or group with all
+the abilities that are mentioned in the table above. They cannot however create
+groups or projects, and they have the same access as logged out users in all
+other cases.
+
+An administrator can flag a user as external [through the API](../api/users.md)
+or by checking the checkbox on the admin panel. As an administrator, navigate
+to **Admin > Users** to create a new user or edit an existing one. There, you
+will find the option to flag the user as external.
