Superset BI workloads are dominated by range scans rather than point lookups where AHI helps. Disabling AHI frees buffer pool memory. Re-enable after profiling with SHOW ENGINE INNODB STATUS if hash searches exceed 10%% of non-hash.

Closes #83

rather than point lookups where AHI helps. Disabling AHI frees buffer
pool memory for actual data pages. Re-enable after profiling with
