Create a new storage pool
Create a simple zpool, a mirrored zpool, a zpool having nested VDEVs and a hybrid zpool with cache and log drives
CLI Example:
.. code-block:: bash
salt '*' zpool.create myzpool /path/to/vdev1 [/path/to/vdev2] [...]
salt '*' zpool.create myzpool /path/to/vdev1 [...] [force=True|False]

salt '*' zpool.create myzpool mirror /path/to/vdev1 [...] mirror /path/to/vdev2 /path/to/vdev3 [...] [force=True|False]
salt '*' zpool.create myhybridzpool mirror /tmp/file1 [...] log mirror /path/to/vdev1 [...] cache /path/to/vdev2 [...] [force=True|False]
