Add action to manage security groups

To manage association between security groups and ports on container, this blueprints proposes adding "Manage Security Groups" action as item action into table view and details view.

This action should use neutron API directly. But horizon does not have Angular module and REST API to manage security group, i.e. corresponding functions for 'openstack port set --security-group <security group> <port>' command. So Zun UI should implement them.
