  - Use Gerrit's WorkQueue for running the DeleteTrashFolder task
    
    The deletion of the trash folders was executed using an unmanaged thread
    which was not visible to the Gerrit admins in the list of tasks.
    
    Rely on the standard Gerrit's WorkQueue so that the deletion of trash
    folders are visible in the tasks and can also be easily managed with
    Gerrit commands, without having to go to a lower level in digging on the
    JVM threads.
