FreeBSD Coding: adduser - User home ZFS dataset creation

Описание: I spent the morning working on FreeBSD's adduser script to add the ability for the script to create a ZFS dataset for the new user's home directory.

This is the first step to supporting ZFS home directory encryption as requested in this PR: https://bugs.freebsd.org/bugzilla/show_bug...

Ideally, I'd like to build support in adding support for ZFS properties into adduser.conf (compression, encryption, recordsize, etc) for automated user adds. For the time being, however, I'm just going to focus on the dataset creation process and just inherit the properties from the parent dataset.

I apologize for the audio quality. There's an echo, probably from competing microphones from AirPods and laptop? Not sure, still figuring out OBS.
