#8566 support newer pwd hashs, remove deprecated 'crypt' AUTH PLUGIN CHANGES
our LDAP plugin's password handling uses crypt which is deprecated since 3.11 and removed in 3.13 https://docs.python.org/3/library/crypt.html
crypt only supports a few algorithms anyway, it'd be good to support argon2, scrypt, bcrypt, pbkdf2_sha512
local password storage does sha256 and definitely should be updated. Similar/same config options for local & ldap hashing?
https://passlib.readthedocs.io/en/stable/ seems pretty good and supports a lot of algorithms, but it isn't maintained the best :(
If an admin configures a new password hashing algorithm, we should make it be a seamless transition, including when someone logs in to re-hash the password, when needed.

QA: After switching to this branch, you should be able to log in as a user, and then see that the password automatically got re-hashed with the new preferred algorithm.
There are breaking AuthenticationProvider plugin changes, for any custom Auth implementations:
