* PASSWORD HASH
The password hash should be an Argon2id hash, which can be generated
via:
$ nix-shell -p libargon2
[nix-shell]$ argon2 "$(LC_ALL=C tr -dc '[:alnum:]' < /dev/urandom | head -c16)" -id -t 3 -k 262144 -p 1 -l 16 -e

$argon2id$v=19$m=262144,t=3,p=1$NFU1QXJRNnc4V1BhQ0NJQg$6GHqjqv5cNDDwZqrqUD0zQ
SHA1 is also accepted, but SHA1 support is deprecated and the user's
password will be upgraded to Argon2id on first login.
Examples:
Create a user with an argon2 password:
$ hydra-create-user alice --password-hash '$argon2id$v=19$m=262144,t=3,p=1$NFU1QXJRNnc4V1BhQ0NJQg$6GHqjqv5cNDDwZqrqUD0zQ' --role admin
