A QP can be created using either the generic interface or a provider
specific interface.
Provider QPs extend the legacy QP, which in Cython means that the
legacy QP's __cinit__ will be called automatically. To avoid QP being
initialized via legacy interface, add **kwargs to QP's __cinit__(). If
kwargs is not empty, the QP's __cinit__ will return without creating
the QP, leaving the initialization to the provider.
