Public bug reported:

An error should be returned when subnet-update is used to modify the
allocation_pool such that existing neutron ports are no longer included.
This operation should not be permitted.

Currently the existing allocated neutron ports are not verified when a
subnet allocation pool is changed.  This can lead to unusual statistics
such as:   there could be 50 allocated neutron objects associated with a
subnet, however the allocation pool range only includes 10 IP addresses
and all 10 of those are not allocated.
