Neutron fails to associate more than 2 floating IPs

[Gil Meir]

Only 2 floating IPs can be associated, when trying to associate more an error is raised.
The issue seems to be caused since the ports (attached to the instances) belong to a different tenant then the floating ip tenant.

A description with how I came to this conclusion will be attached next.
A snapshot is attached.

I must mention here that the size of the pool of floating ips is missing one address as described in the attached file fuel_floating_ip_5.1.1_bug.txt:
The range of addresses set in Fuel UI is 10.209.25.65-10.209.25.77, but 10.209.25.65 doesn't appear there.

Please investigate this too and create a bug if needed.

The issue from #2 is that neutron ports are created with admin tenant and floating IPs with services tenant, resulting in the following message:
400-{u'NeutronError': {u'message': u'Bad floatingip request: Port d3aab132-ea72-4b0a-883a-ae6a3feb08bb is associated with a different tenant than Floating IP 19211506-7817-4a0d-bff1-e6516c3f47b3 and therefore cannot be bound.', u'type': u'BadRequest', u'detail': u''}}

https://review.openstack.org/#/c/137067/1/deployment/puppet/neutron/manifests/network/predefined_networks.pp shows that the tenant for floating IP pool changed from admin to services.

    Allocate floating IPs for correct tenant

    Search for floating IP tenant name and use
    it when allocating IPs, thus allowing
    user to use IPs from configured tenant
    and not from services tenant
