Prefix bloom filters

[zaidoon1]

Similar to rocksdb: https://github.com/facebook/rocksdb/wiki/Prefix-Seek#configure-prefix-bloom-filter, it would be great if have the ability to add prefixes to bloom filters and use them during prefix seeks to filter out reads for prefixes that don't exist in the db. It would be even better if we can customize is so that for a given key, we can add multiple prefixes. See facebook/rocksdb#12824 for context
