Optimize queries for port operations
Port create/update are most time-consuming operations
on subnet creation. As example, in those cases where
several subnets are created over the same network the
response time for those port operations is linearly
increased as the total subnets increases.
This patch improves the number of queries required on port
operations in order to reduce the response time.

Title:
Response time increasing on new subnets over same network
Status in neutron:
Fix Released
Bug description:
After some subnets created over same network, response time for new
ones is incresase linearly, if number of subnet is elevated (over
1000) timeout is triggered.
The issue can be easily reproduced by creating subnets in a loop and
capture the time it takes to create as the total count increases.
