port "Improve project overview UI" to EE

See merge request gitlab-org/gitlab-ee!6844

In a file called `CODEOWNERS` in the root of a repository, in the
`docs/`-folder or in the `.gitlab/` folder it is possible to define
users that are 'owners' for specific code paths.

A pattern can be defined on each line in the same way as it would in a
`.gitignore` file. After that, one or more users can be specified
using their username (using the `@username` format) or email address
linked to their account. Comments can be preceded with a `#`. If a
filename starts with `#` this can be escaped using `/#`.

For example:

    # All files in the `docs/` directory should be reviewed by a
    # technical writer:
    docs/* @jane @joe

    # Ruby files should be reviewed by a backend maintainer:
    *.rb alice@development.gitlab.org

The code owners will be displayed when viewing a blob, if a user for
the username/email cannot be found, nothing will be shown.

When multiple patterns match the blob being viewed, the last entry
will be used.
