Compare performance of side nav cluster list pre and post SSP change

[richard-cox]

• Add server-side pagination to home page cluster list #11663 brought in a change in how the side nav calculates the clusters to show
• Previously a computed property references mgmt and prov cluster lists and would re-run on changes (like a cluster coming online / going offline)
• Now there is a set of watches on mgmt and prov cluster lists (which had to be deep). We should confirm that the amount of times the update runs given those changes aligns with the amount of times the computed properties ran before
• Note - this only affects the world with SSP turned off
