Hello,
I noticed that `CommonPasswordValidator` has a very high memory usage.
Loading the `piotrcki-wordlist-top10m.txt` list that has `9872702` entries
causes a 755M usage even though the disk size of the list is only 87M.
Since `CommonPasswordValidator` basically only needs to check for
membership, I think that using a variant of a bloom filter would be much
better than using a hash table (`set()`).
