I want this functionality as well. We have hardware load balancers that have 100's if not 1000's of vips. Trying to correctly guess the initial subnet size and then not being able to grow the subnet makes this highly impractical. Allowing us to specify the network_ID to use for the load balancer creation and then the plugin choosing the subnet that has available IP's is a much better route. It also aligns to how floating ip's work in neutron.

This allows us to add subnets to the lbaas network pool dynamically and eliminates people needing to know the capacity levels on each specific subnet. It also eliminates the confusion and frustration of trying multiple times with different subnets before they get an LB that can provision. Furthermore their is no API for people to be able to get subnet capacity, so in large deployments this becomes highly impractical and frustrating.
