Is your feature request related to a problem? Please describe.

• recently i was looking at 2.5k pods in pods list, with default page size of 100, grouped by namespace
• in order to understand which namespace contained the majority of the pods (to debug why so many) i had to use the ns filter

Describe the solution you'd like

• this isn't a biggy, but we should have the pods by namespace in the counts object and it would be super convenient to show that in the group tag Namespace: cattle-system (1519)
• i think we could do this generically for all grouped by namespace groups
• we could do for all other ways to group with vai off , but not with vai on. for this reason i think we should just stick to group by namespace
