Adding fstype zfs and zpool creation options

[Chewbakka-Wakka]

Much like btrfs i.e.
part btrfs.boot --fstype=btrfs --size=1024
part btrfs.rpool --fstype=btrfs --size=1024

btrfs /boot --name=boot --label=boot btrfs.boot
btrfs / --name=root --label=rpool btrfs.rpool

Syntax can be much identical:
part zpool.boot --fstype=zfs --size=1024
part zpool.rpool --fstype=zfs --size=1024

zpool /boot --name=boot --label=boot zpool.boot
zpool / --name=root --label=rpool zpool.rpool

The issue is at this time... that we need zpool/zfs modules loaded installed in order to perform such actions.
Although greater adoption of ZFS on root has become possible, this is quite some process... https://openzfs.github.io/openzfs-docs/Getting%20Started/Fedora/Root%20on%20ZFS.html

As the linked post mentions incompatiblities around kernel, maybe that's the first thing that should be ready before we try with the installer.

Other than that little bit ;-) First, we need support in blivet, because that's what does storage for us. Then, the rest can follow, anaconda and pykickstart in tandem. Since zpools are another kind of container, that's a bit taller order than just a new filesystem. But btrfs already is such a thing, so hopefully there's a template to follow.
