Despite what Nova's api-ref currently says [1], the 'addSecurityGroup'
action only requires a security group name if using nova-network: it
will happily accept either a name or ID if using neutron.
We are using 'Proxy._get_resource' to allow users to pass either an ID
or an 'openstack.network.v2.security_group.SecurityGroup' object
(there's no implementation of Nova's deprecated SecurityGroup resource).
If given an ID, this help method will only populate the 'id' field of
the created resource. Thus, we need to use this if provided.
