    ScaleIO: Deprecate sio_allow_non_padded_thick_volumes

    The config option sio_allow_non_padded_thick_volumes was added to
    allow sites to continue to have non-padded thick volumes after it was
    disabled by default due to security concerns. At the time it was only
    thought to be an issue with thick volumes, but has since been determined
    to also be an issue with thin.

    To address the concerns with thin, the general option
    sio_allow_non_padded__volumes was added, making the thick-only option
    redundant. This new option was added without the deprecation of the
    thick-only option to ease backporting to address the securty concern,
    but we now want to work towards removing the thick option so we can just
    have the one option for both provisioning types.
