I can't see traffic on Pod-Traffic dashboards, but that would be a separate issue..

We should remove/replace this in dashboards:

"content": "# Network Observability Metrics\n\nUse this dashboard to visualise metrics from the Network Observability add-on for AKS. Dashboard displays metrics from Linux and Windows Clusters. To hide the irrelevant metrics, simply collapse the unwanted sections. Alternatively, you can edit the dashboard to delete unwanted panels. For any questions or issues, please see our documentation.",

Can we remove any other mentions of AKS / netobs addon? For instance, the documentation link ought to point to retina

I'm pretty sure I have covered this. But I'll do another search everywhere to make sure I didn't miss anything.

All mentions to network observability (names, tags and documentation) have been updated to point to Retina in the last commit.
