Revert neuvector upgrade

General MR

Summary

!4008 (merged) was merged in, but has issues. This reverts those changes, and we'll reopen that MR and issue.

I think the neuvector merge that I pulled in this morning is actually broken -- even thought the pipelines passed . I believe the new neuvector-prometheus-exporter-pod IB image is broken. The pod doesn't come up, it errors -- but somehow the pipelines pass despite the pod's error. I'll revert this commit into BB, and re-open for more work

Pod error message:

Controller found.
Traceback (most recent call last):
  File "/usr/local/bin/nv_exporter.py", line 2, in <module>
    from prometheus_client import start_http_server, Metric, REGISTRY
ModuleNotFoundError: No module named 'prometheus_client'

We expect to see:

Controller found.
Login to controller ...
Start exporter server ...
Register collector ...
