    Test alloc_cands with indirectly sharing RPs

    There are two new test cases proposed in this patch about shared RPs.
    The generic setup in both cases are the following:

           CN1 (VCPU, MEMORY_MB)
         / \
        /agg1 \agg2
       / \
      SS1 ( SS2 (
       DISK_GB) IPV4_ADDRESS
                  SRIOV_NET_VF)

    In the first case we only request resources provided by SS1 and SS2
    but not CN1. In the second case we also request resources from CN1
    besides requesting resources from SS1 and SS2.

    The first case had been broken before nested providers are supported.
    But this is fixed now thanks to the following commit, which enables
    getting nested providers as well as sharing providers.
