[GENERAL] Use readiness container v3.0.1

Readiness container v3.x and up are now present in ONAP main repository.
They're also not using root user anymore and then script path has
changed.
Finally, "job_complete" script has been integrated in main "ready"
script.
As those changes are significant, we must upgrade all the components at
once.
