Use tempest-full in the integrated gate

tempest-full now matches the legacy-tempest-dsvm-neutron-full job.

Known differences are:
- there's no reproduce.sh
- the log path is <inventory_name>/logs as opposed to just logs
- there's no static log description page (which was stale anyways)

This replaces legacy-tempest-dsvm-neutron-full with tempest-full
in the integrated gate template.
