What this PR does:
When performing large queries the frontend can create over 100k queries which causes a lot of subsequent work. There are a lot of opportunities for improvement here. This PR addresses allocations due to repeatedly converting the same dedicated columns objects to proto and then to json by memoizing the results and storing them by hash.
Also, noticed an old note to add tests and a small perf improvement for the query builder.
