Can't use MemCached for query cache because of big key size.
Description
Mem Cache keys are limited to 250 characters, but a lot of queries are a lot bigger than that. This usually means that we need to hash the key itself. Probably MD5 would be the best solution, with check to see if the key size if beyond 250 (to reduce perf of hashing).
