Only first Tempest gate result retrieved after multiple tests

[Julian Montez]

Running the `/opt/openstack_tempest_gate.sh` script on the designated Tempest utility container only delivers the first testrepository subunit stream.

All test results are archived, with filenames incrementing from zero, but the first result is hardcoded to be copied for a deployment node to retrieve (https://github.com/stackforge/os-ansible-deployment/blob/39409db9b9caea199fd61110f348c0be209e6754/playbooks/roles/os_tempest/templates/openstack_tempest_gate.sh.j2#L189-L190).

Using the `testr` CLI, the last result can be used in conjunction with its own subunit stream utility to ensure the latest results are delivered to an end user.
