zfs pool and fs properties are not passed to zfs.zpool_create

In curtin/block/zfs.py the definition of zpool_create is

def zpool_create(poolname, vdevs, mountpoint=None, altroot=None,
                 pool_properties=None, zfs_properties=None):

But this method is called from curtin/commands/block_meta.py without the pool_properties and zfs_properties:

    zfs.zpool_create(poolname, vdevs_byid,
                     mountpoint=mountpoint, altroot=altroot)

So the properties defined in the configuration file are never applied to the pool.

Besides the documentation specifies that zfs filesystem properties are set with fs_properties while in the code it's called zfs_properties. It'd be more consistent to name them identically
