    Don't require quantumclient when running nova-api.

    Handle ImportErrors's when importing the quantumv2 API
    in the Nova API servers controller. This makes it possible
    to run nova-api when quantumclient is not present.

    This was recently broken in commit 83a8418 which changed how we
    import the quantum v2 API class.

    Fixes LP Bug #1070509.
