Bump testsuite 1.7.0 for Guilin

It consists mainly in simple robot changes
It is far from our target for the moment
- chart not brought back to OOM repo
- baseline image too big
- pod launched as root
- pod still dealing with python 2.7

A refactoring of the pod was planned for Guilin but it is not ready.

Note: The changes are already taken into account in CI through the
xtesting dockers
