refstack client integration

JIRA: DOVETAIL-366
JIRA: FUNCTEST-758

usage:
1,functest testcase run refstack_defcore, will run the
default testcases in defcore_201608.txt
2,cd <path>/functest/functest/opnfv_tests/openstack/refstack_client
  python refstack_client.py -c <tempest-conf-file-path> --testlist <testlist-path>

this has been worked with openstack-refstack experts, etc.
tested workedi.
result see http://paste.openstack.org/show/602173/
