ITS#8575 Implement argon2 password hashing as a module
This change implements argon2, which won the Password Hashing Competition (https://password-hashing.net/) as a contrib-module in order to provide a modern password hashing alternative in openldap. The currently available password hashing algorithms are relatively old, and modern hardware, especially GPUs can compute quite a few (ranging from tens of thousands to millions) of hashes per second. Argon2 was designed to withstand such attacks. This implementation uses the default work factors used in the argon2 command line client, but the resulting hashes are stored in a way that would allow retroactive changes to these values, or even exposing them as configuration in the module.
