Update test_trunk after adding new ip command tool.
A new tool has been added to wrap with ip command line tool. https://review.openstack.org/#/c/613310/ This tool implements methods to list VM adrresses and to configure VLAN device interfaces via an SSH connection. This refactor trunk test case to improve code readability and make this test to use shared code base with other test cases to be written in the future related with trunk related scenarios.
