Arvind Somya 12f18ddbcf Change hard coded numbers to constants in security group tests
Security groups tests in Neutron contain a lot of hard coded HTTP return codes
and protocol numbers. These should be changed to use constants.

Change-Id: Ibecff3821c54f12848a05648f35381a0c73a0896
Fixes: Bug 1218928
