    Use SensitiveStringField for BlockDeviceMapping.connection_info

    bd977f400a1192d5cf7c2b52ef91615c0828813c added the SensitiveStringField
    to oslo.versionedobjects. SensitiveStringField is a StringField, which
    is what BlockDeviceMapping.connection_info was already using. The difference
    is that a SensitiveStringField masks passwords in the 'stringify' method,
    which is what's used when __repr__ is called on the object.

    Since BDM.connection_info can contain credentials, and the connection_info
    dict gets passed around quite a bit in the compute manager and virt drivers,
    it has from time to time gotten logged without first masking passwords.

    This makes the object handle masking the password so we don't have to do it
    explicitly anymore.

    There is no version bump on the BlockDeviceMapping object since nothing has
    functionally changed.
