NUMA topology _get_constraints_auto assumes flavor object

[Nikola Đipanov]

Resulting in AttributeError: 'dict' object has no attribute 'vcpus' if we try to start with a flavor that will result in Nova trying to decide on an automatic topology (for example providing only number of nodes with hw:numa_nodes extra_spec)

    NUMA _get_constraint auto assumed Flavor object

    We call this code in the API that is not converted to using objects at
    the moment, so we cannot assume attribute access for dicts.

    We also make sure that tests exercising it will fail by using dicts
    exclusively until the code is converted to objects.
