Make use of Dracut's ability to restore the initramfs on shutdown and
pivot to it, allowing for a clean unmount and export of the ZFS root.
No need to force-import on every reboot anymore.

60-zpool.rules was retired some time ago in favor of 69-vdev.rules.
Additionally, there is no guarentee a zpool.cache file exists so
only install it conditionally upon its existance.

In the interest of maintaining only one udev helper to give vdevs
user friendly names, the zpool_id and zpool_layout infrastructure
is being retired. They are superseded by vdev_id which incorporates
all the previous functionality.
Documentation for the new vdev_id(8) helper and its configuration
file, vdev_id.conf(5), can be found in their respective man pages.
Several useful example files are installed under /etc/zfs/.
/etc/zfs/vdev_id.conf.alias.example
/etc/zfs/vdev_id.conf.multipath.example
/etc/zfs/vdev_id.conf.sas_direct.example
/etc/zfs/vdev_id.conf.sas_switch.example

Closes#981
Relying on an /etc/hostid file which is installed in the system
image breaks diskless systems which share an image. Certain
cluster infrastructure such as MPI relies on all nodes having
a unique hostid. However, we still must be careful to ensure
the hostid is syncronized between the initramfs and system
images when using zfs root filesystems.
To accompish this the automatically created /etc/hostid file has
been removed from the spl rpm packaging. The /etc/hostid file
is now dynamically created for your initramfs as part of the
dracut install process. This avoids the need to install it in
the actual system images.
This change also resolves the spl_hostid parameter handling
for dracut.

This ensures that module-setup.sh script will always be able to
install the required dracut components regardless of how the zfs
package was configured.
