get_floating_ip_pools for neutron v2 API inconsistent with nova network API

[Salvatore Orlando]

Commit e00bdd7aa8c1ac9f1ae5057eb2f774f34a631845 change get_floating_ip_pools in a way that it now return a list of names rather than a list whose elements are in the form {'name': 'pool_name'}.

The implementation of this method in nova.network.neutron_v2.api has not been adjusted thus causing tempest.api.compute.floating_ips.test_list_floating_ips.FloatingIPDetailsTestJSON to always fail with neutron

The fix is straightforward.

    Neutron v2 API: fix get_floating_ip_pools

    Commit 7254f9b9dfbadadeb3aeda5d02bf37bfeb65e72d changed this method
    in nova.network.api in a way that it now returns simply a list of
    floating ip pool names, rather a list of dicts in the form

    {'name': 'pool_name'}

    The implementation of get_floating_ip_pools for neutron needs to
    be changed accordingly. Otherwise nova's floating ip extension
    will return a dict as floating ip pool names when neutron is enabled.
