    Remove VxFlex OS credentials from connection_properties

    VxFlex OS password is not stored in block_device_mapping table.
    Instead of this passwords are stored in separate file and are
    retrieved during each attach/detach operation.

    The stable/rocky branch is in Extended Maintenance mode and is no
    longer released from. If you decide to apply this patch to your
    deployment, you must make a corresponding change to the os-brick
    library. You can find the os-brick patch for stable/rocky here:
        https://review.opendev.org/#/c/733103/

    Additionally, you must deploy a new configuration file on compute
    nodes, cinder nodes, and anywhere you would perform a volume
    attachment in your deployment. See the documentation change on
    this patch for details about the new config file.
