Nova API gateway needs to finish two tasks for security group functionality. One is to create security group in bottom pod if it does not exist. Only when the user boot a server can we know which pod to create the security group. The other one is to handle default security group. We decide to replace the default "remote group" rules with several "remote ip prefix" rules. Each rule points to a CIDR of one of the project's subnets. Since the collection of subnets may change, we need to update bottom security group rules. Currently these two tasks both run in synchronous way. For better response time the second task can be implemented in asynchronous way later. Neutron plugin part for security group functionality will be covered in next patch.
