    Fix allocation_candidates not to ignore shared RPs

    When both the compute node resource provider and the shared
    resource provider have inventory in the same resource class,
    AllocationCandidates.get_by_filters didn't return an
    AllocationRequest including the shared resource provider.

    To fix the bug, this patch changes the function of
    _alloc_candidates_with_shared() to consider resources from
    non-sharing providers and resources from sharing providers
    at the same time.
