Add functional tests in verify and merge

As Ana said ,"The first functional test should be as simple as a "Hello world",
 it shall be possible to run the "Hello world" test without using OpenStack."
so i just finish functional test framework and do functional test for subcommand
"runner"and"scenario" without using Openstack.
