Fix failure in multi-chunk state sync for nicira plugin

Bug 1224719

This patch ensures the 'result_count' attribute from NVP API responses
is properly handled, and adds support for '_page_cursor' request query
parameter in the fake nvp api client in order to ensure issues like this
are captured by unit tests.

Fix haproxy agent unit test to be runnable alone by tox

haproxy agent uses periodic_interval option that can interfere
with the same option declared in neutron/service.py when running
'tox services.loadbalancer'

FWaaS - fix policy association of firewall rule

If an existing firewall rule already associated with a
firewall policy is associated with a different firewall
policy, the new association should fail. The check for
the existing association was not being made, hence the
firewall rule was being removed from the older policy
and being associated with the newer policy (incorrect
behavior). This is being fixed here.

If the association with the newer policy has to be made
the rule should first be removed from the existing policy
association.

_validate_network_tenant_ownership must be less strict

Neutron, currently does a strict validation code
so that for non-shared network the subnets and
ports must belong to the same tenant as the network. In
the case of a "service VM" created by
admin user, this function should return thus allowing
admin users to create ports and networks in a tenant
network.
