Ignore namespaces in viz

[thedodd]

What problem are you trying to solve?

The viz dashboard is nearly unusable once the K8s cluster reaches a certain threshold of namespaces. In the case where K8s is being used to host workloads for customers, each in its own namespace, this problem may quickly arise.

How should the problem be solved?

Many of our namespaces have no linkerd connectivity, so being able to ignore namespaces via blocklist, glob patterns, or to manually specify an acceptlist of namespaces, all seem like valid solutions.

Any alternatives you've considered?

N/A

How would users interact with this feature?

This would be specified in the helm chart deployment, most likely.
