ci: remove unused volumes after e2e tests and remove logs collection (#246)

In this PR, we fix the ci error indicating we reached the number of
volumes allow by deleting automatically after tests the volumes.

We also remove the step that collect logs because the container that are
interesting to us to debug are being removed entirely. Therefore the
logs from the nodes are not being collected in this step.
