feat(helm): add networkPolicy for miw

fty4 commented 8 months ago

Description

This PR will add a networkPolicy to restrict the access to the miw pods. In the default implementation access from every namespace is allowed (empty ns selector):

from:
  - namespaceSelector: {}

We also need this change to allow network traffic because the default setting will deny everything. Other etx repos already use networkPolicies.

I would be delighted if this could be merged and released soon.
