Add zfs_prepare_disk script for disk firmware install

Browse Source 
Have libzfs call a special `zfs_prepare_disk` script before a disk is
included into the pool.  The user can edit this script to add things
like a disk firmware update or a disk health check.  Use of the script
is totally optional. See the zfs_prepare_disk manpage for full details.
