Update VM build3.4.0

build VM to adapt to new ci/cd workflow.
The VM image is built on gerrit verify when the image is not present in google storage.
It is not uploaded yet on google storage.
The build + upload of the new VM image is done after the review is merged.
For details on how this is done, refer to ./jjb/nfvbench/nfvbench.yaml in the opnfv releng repository.
