    Added overwrite warning for db_export_metadefs.

    The bug in [1] proposed to always require a directory option for
    glance-manage db_export_metadefs command. The rationale being that
    silently overwriting the default path /etc/glance/metadefs can
    be undesired. However, the feedback was that this command should
    stay silent in case it's called from cron jobs or automated tasks,
    and that it's better to simply log a warning and proceed, as well
    as update the documentation with a cautionary note. This patch
    addresses that request.
