The review:
* adds a python3 job in order to test the refstack-client with
python3 as well.
* adds a job which runs unit tests by python3.7
* changes default python3 (when -p 3 is specified) in setup_env script
to version 3.6.0
* converts downloaded list of tests from bytes to str in order to unify
the types used for python2 and python3 compatibility.
* edits -p argument in the setup_env script so that it also accepts a full
version of Python a user wants to run with, before there were 2 options:
* python2.7.8
* python3.6.0
* sets object-storage.operator_role to Member in tempest.conf in order to run
tempest.api.object_storage.test_container_services.ContainerTest tests
