Public bug reported:

When the `member_of` parameter is present, only non shared providers in
the specified aggregation are picked, but the non shared provider brings
shared providers from out of the specified aggregation.

For example, with the following set up,

```
               CN1 (VCPU)                   CN2 (VCPU)
              / agg3         \ agg1        / agg1         \ agg2
     SS3 (DISK_GB)      SS1 (DISK_GB)          SS2 (DISK_GB)
```

When you request allocation candidates in "agg3" using `member_of` parameter,
expected is to get one allocation request of the combination of (CN1+SS3),
but actual is to get two allocation request, (CN1+SS3) and (CN1+SS1).
