The neutron CLI command reports of 8 floating IPs available for
allocation in the whole cluster,

yet in the Horizon the default quota value for 'floating_ips' is shown
(equal to 50).

This is confusing because once 7 floating ips are allocated, all
subsequent allocations fail, yet User doesn't understand that this is
caused by pool exhaustion since he relies on <Default FIP Quota> -
<Number of allocated FIPs>

The minimum between the FIP Quota value and the Quantity of actually
available FIPs should be shown in Allocate FIP form.
