This pr proposes adding support for Argon2 besides SHA256 for credentials.
Argon2 seems to be widely used and is the recommended way of storing passwords by owasp at the moment.
To support both argon2 and sha256, I've moved some of the validation logic into the Credential struct. This way the rest of the codebase doesn't need an understanding o the different configuration options.
