    Enable rgw trust forwarded https when https proxy

    This option is required for server-side encryption to be allowed
    if radosgw is behind a reverse proxy,
    such as here when certificates are configured and apache2 is running.

    ref. https://docs.ceph.com/en/latest/radosgw/encryption/

    It is safe to always enable when https is configured in the charm,
    because it will be securely behind the reverse proxy in the unit.
    This option must not be enabled when https is not configured in the charm,
    because this would allow clients to spoof headers.
