Description

his PR adds a ciliumnetworkpolicy that is equivalent to the standard networkpolicy already present in the templates. As cilium usage as a CNI is rising and the usage of ciliumnetworkpolicies is more and more widespread, having the possibility to deploy those directly from a setting in the values would be a time-saving option for a lot of deployments.

As this PR adds a new condition for the already existing networkpolicy, this is a breaking change for those using the chart with networkpolicies enabled as they'll have to add the new field to their values file.

Motivation and Context

As I tried to use minio alongside loki on a cluster which was using cilium as its CNI, the minio pod was not able to work properly. Especially the job supposed to interact with the main minio pod was not able to complete so I had to manually create a cilium netpol.

How to test this PR?

One may ltemplate the chart or even deploy it to a cluster with cilium as the CNI to make sure the pod is running as expected and the job is able to complete.
