Enable a user to set their visibility level just like in projects.
If a user's visibility level is not set to private for instance, visiting /u/username should direct me to a 404 page which prevents leaking of information about any existence of the user.
There is an active MR on setting the visibility level for groups(https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3051) hence I think the implementation would be similar
