Port NetworkPolicy flavour to Kustomize

[NimJay]

Background

• This is part of Add kustomize support #536.
• We want create Kustomize Components for each flavour of Online Boutique — where possible.
• This pull-request is specifically for /docs/network-policies.

Change Summary

• This pull-request ports over the flavour with NetworkPolicy resources to Kustomize.

Testing Procedure

1. Check out the source branch:

git checkout nimjay-kustomize-network-policy

2. Uncomment the network-policy Kustomize Component inside kustomize/kustomization.yaml.

sed -i '' 's/# - components\/network-policy/- components\/network-policy/' kustomize/kustomization.yaml

3. Check that Kustomize builds correctly.

# This is the same as "kustomize build".
kubectl kustomize ./kustomize/

4. Check that the Kustomize build output includes the NetworkPolicy resources.

kubectl kustomize ./kustomize/ | grep NetworkPolicy

You'll notice that the NetworkPolicy resources are included in the Kustomize build.

I've removed the step:

gcloud container clusters create \
    --enable-dataplane-v2

because these GKE-specific instructions are already documented in the GKE official docs. We should link to those docs are much as possible — so we're relying on TWs' work as much as possible. :)

(I'm open to bringing it back.)

I've removed "+ OnlineBoutique" since I think it might be redundant (since we're already in the Online Boutique repo). I'm open to bringing it back.

The goal is to a add each and every Kustomize Component here:

  # - components/name-of-component

for convenience and so we could easily use sed to uncomment.
