healthchecker - New navigation approach for healtherchecker report : cluster/bucket/node vs cluster/node/bucket

Perry suggests:

I see that we've already got the hierarchy built-in, but putting everyone into one flat page makes it hard. Drop downs of "cluster" to "bucket" to "nodes" would be good, as well as "cluster" to "nodes (aggregated for each bucket on the node)" to "bucket" would help. It might be too much work, but structuring and reusing the formatting of our own UI might be a nice tie-in here as well.
