Make complete Network Policy example

Problem to solve

We currently have incomplete network policy examples in the documentation. Expanding the examples to be full generic network policies would be good.

Further details

• This would allow customers to have a base to build upon when setting network policy for their specific instance.
• It would eventually help us set workable defaults.
• It helps demonstrate the network relationship between components.

Proposal

• Create network policies for a test instance and document them as an example.

Who can address the issue

• anyone

We are currently implementing k8s network policies, based on the component-diagram.

In order to further improve the security on GitLab, we would like to get all the intra-namespace network policies. Im assuming that this is know to you, but for users it's really hard to get the overview. Ideally, this could be part of the Helm charts.

Is it in the roadmap of GitLab to provide the complete network policy in the charts? It could be part of every release, and whenever connectivity in this regards would change, the policies would be updated accordingly.
