Add API test for normalized CIDR attribute in the SG rule

This patch adds test which replaces fullstack test:
neutron.tests.fullstack.test_securitygroup.SecurityGroupRulesTest.test_normalized_cidr_in_rule

It is simple API test which can be done quickly in
neutron-tempest-plugin job. In fullstack instead it requires to prepare
whole environment with neutron-server, fake compute
node, agents, etc. so it takes much more time.
