ConnectionValidator calls userInfo and rolesInfo, but uses an integer instead of a Boolean for the showPrivileges and showBuiltinRoles arguments, per the MongoDB documentation:
https://docs.mongodb.com/manual/reference/command/usersInfo/
https://docs.mongodb.com/manual/reference/command/rolesInfo/
We should convert that to use Booleans.
