Add benchmark test for SuggestionsEngine.reloadSuggestions #311
Description
It occurred to me that the testing I did with AirConcurrentMap could have been better validated if I had had a benchmark test against the SuggestionEngine.
This is relatively straightforward to do and folks can use the existing BenchmarkGSetFiltering code with minimal changes to achieve this. I'll leave this up if anyone wants to tackle it or else I'll do it myself.
