maybe use e2e.StartAndWaitReady() here, relying on sidecar's health endpoint as readiness check to make sure we have a running sidecar before testing?

Can update here or default readiness to false at the beginning of runSidecar()

Changes
Update ready state in "fetch prometheus version" loop - Currently, if no ready Prometheus behind sidecar then this loops indefinitely and never sets sidecar as
not ready. As a result, sidecar reports asreadyif it starts up and there is not a running Prometheus behind it.Verification
