What does this PR do?

Enable the network and disk v2 checks by default for windows and linux so python runtime will only be needed for additional integrations.

We've tested this on internal clusters for the past couple weeks and everything looks good.

Motivation

Describe how you validated your changes

These have been running on internal clusters for weeks now.

Looks like the unit tests are failing because they rely on these values being false by default, see here and here.

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

  • ✅ = significantly better comparison variant performance
  • ❌ = significantly worse comparison variant performance
  • ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

  1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

  2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

  3. Its configuration does not mark it "erratic".

we are in diskv2 folder, don't we want to set it to true ?

use_diskv2_check takes precedence over disk_check.use_core_loader in the code
Ie. if use_diskv2_check: true then we actually use the Go v2 check instead of the Python check, no matter the value of disk_check.use_core_loader
Which is quite counter intuitive though 😄

I think your comment still reveals an issue, we're testing something which can't happen here: if use_diskv2_check is false then the v2 code is unreachable, so there is no point in checking (and testing) that here

I think we can just remove the test and the whole condition at the beginning of Configure in diskv2 (btw there is no equivalent in networkv2)

this is testing that an error is thrown when trying to initialize the diskv2 check when it shouldn't be used. It maybe should just be deleted instead
