Public bug reported:

[Summary]
floating ip info does not contain information about associated instance if nova-network is used.
behaviour was changed between 11.05.16 and 21.06.16

[Topo]
devstack all-in-one node
libvirt+qemu
nova-network

[Description and expect result]
floating ip info contains information about associated instance as in previous releases.

[Reproduceable or not]
reproduceable

[Recreate Steps]
0) source any credentials. Result is the same for demo credentials of devstack (user=demo project=demo)
and for admin credentials.

1) boot instance
nova boot --image cirros-0.3.4-x86_64-uec --flavor 1 ttt

2) create floating ip
nova floating-ip-create

3) associate floating-ip
nova floating-ip-associate ttt 172.24.4.1

4) list intsances
nova list

+----+------------+-----------+----------+--------+


[Root cause anlyze or debug inf]
- database contains information about floating ip and record has a correct id of fixed ip
- database contains informtaion about fixed ip and record has a correct instance uuid

nova 'os-floating-ips' rest api calls network_api.get_floating_ips_by_project
it calls objects.FloatingIPList.get_by_project
it retrieves floating ips from DB and calls obj_base.obj_make_list for each record
obj_make_list calls _from_db_object of passed type and creates FloatingIP object

_from_db_object takes 'fixed_ip' as expected attributes but only
FloatingIP.get_by_id passes it.
