Following this [https://forum.djangoproject.com/t/stop-increasing-default-
pbkdf2-iteration-count/25539/7 forum thread on password hashers
iterations/parameters], it was agreed that the current `parallelism`
parameter for `ScryptPasswordHasher` should be increased to 5.
Alternatively we could switch to `N=2^16 (64 MiB), r=8 (1024 bytes), p=2`
or `N=2^15 (32 MiB), r=8 (1024 bytes), p=3`.
