    Fix for race condition in security groups creation

    There was a race condition in the creation of default security group,
    which was exposed when neutron was able to create a default security
    group and backend controller fails which results in inconsitency between
    neutron and backend controller.
    This fix will allow both neutron and backend controller to rollback
    in case of any failure i.e. either on neutron side or backend
    controller to maintain consistency between both. It also removes the
    strict checking for one default security group per tenant and will allow
    neutron to handle this scenario
