this patch was only to evaluate... I think we would need to embellish this
patch to save the setting in the system table, before committing this patch.
Hmm, then again, it's a chicken and egg thing. You can't read the setting if
the setting is wrong in the yaml.... kind of bad. Perhaps system table settings
should always be hashed with MD5, and this setting only applies to user
keyspaces.
