ci: [WIN-NPM] windows validation script run on CAPZ

[huntergregory]

Reason for Change:
Scripts for validating NPM Windows.

Issue Fixed:

Requirements:

• uses conventional commit messages
• includes documentation
• adds unit tests

Notes:

New Changes

1. Use official Cyclonus binary instead of a fork.
2. Add scale tests that use KWOK, which simulates Pods/Nodes without using actual resources.
3. Creates a .ran file if a step is run, and creates a .success file if a step succeeded. There is also an npm-e2e.ran file that indicates that the npm e2e was run at all, and an npm-e2e.success that indicates that all steps succeeded.

KWOK Installation

VM will need to have KWOK installed:

KWOK_REPO=kubernetes-sigs/kwok
KWOK_LATEST_RELEASE=$(curl "https://api.github.com/repos/${KWOK_REPO}/releases/latest" | jq -r '.tag_name')
wget -O kwok -c "https://github.com/kubernetes-sigs/kwok/releases/download/${KWOK_LATEST_RELEASE}/kwok-$(go env GOOS)-$(go env GOARCH)"
chmod +x kwok
sudo mv kwok /usr/local/bin/kwok

Overall Script Flow

Configuration

1. Installs NPM on Calico CNI.
2. Installs a simple Deployment with 1 Pod.
3. Configures nodes for testing (e.g., cordons all but one node).

Steps

If any step fails, the script should fail and not run following tests.

1. Check VFP is in sync with HNS (filename: vfp-state-prior.ran)
2. Run Cyclonus (filename: cyclonus.ran)
3. Check VFP is in sync with HNS (filename: vfp-state-after-cyclonus.ran)
4. Run Conformance (filename: conformance.ran)
5. Check VFP is in sync with HNS (filename: vfp-state-after-conformance.ran)
6. Run scale + connectivity test (filename: scale-connectivity.ran)
7. Check VFP is in sync with HNS (filename: vfp-state-after-scale.ran)
