[Gitlab System User <gitlab src gnome org>]

commit 241dd80ad5d47a2623989d896ef14f7f4d6c6185
Author: Florian Müllner <fmuellner gnome org>
Date:   Fri Jul 28 13:02:36 2017 +0100

    tool: Add 'import' command
    
    Until we do proper log migration inside Polari itself, this allows
    for importing the DB with the existing logs from telepathy-logger.
