Previously, stack updates would result in an OS::Neutron::Port resource being replaced when the property values were changed in the following ways:
1. The network property referred to the same network, but by name instead of UUID, or by UUID instead of name.
2. Specifying the network using the 'network' property instead of the deprecated 'network_id' property, or sing the deprecated 'network_id' property instead of the network property.
With this update, the OS::Neutron::Port property is updated in-place instead of being replaced.
