Pass security group id to novaclient while adding security

group to server

In AddServerSecurityGroup, we currently pass the security group
name to novaclient. If multiple security groups with same name
exist, then even while passing secuity group using id to
command 'openstack server add security group <server> <group>'
it results in error 'Multiple security_group matches found'.
Added unit test case to test the command.
