DAOS-11375 object: add daos_obj_generate_oid_by_rf2

[wangshilong]

Now we have two different fault domains: rank and node. daos_obj_generate_oid_by_rf() use default fault domain which might be wrong. Eg, creating container(with rf_lvl:1)

Introduce another helper daos_obj_generate_oid_by_rf2() which is aware of fault domain.

can you please explain how this domain plays into the oclass selection?

See dc_set_oclass() for example number of domains affects group size when object class is unknown, and we have check to compare number of domains and group size, it will return invalid if grp_size > domain_nr.

So it is quite important to get correct number of domains when generating OID.
