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.

    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.
