Added auto-replace FMA test for the ZFS Test Suite

Browse Source 
Also included are updates to auto-online test

Automated auto-replace test to go along with ZED FMA integration
(PR 4673) auto-replace_001.pos works using a scsi_debug device
(the only usable virtual device currently due to whole_disk var
needing to be set)

Functionality for automated FMA auto-replace test to work with
scsi_debug devs:  Some functionality/exceptions needed to be
added for automation of auto-replace to work correctly.

In the test an alias vdev_id rule is added for any scsi_debug
device which sets the phys_path="scsidebug" after a udevadm
trigger command.

A symlink is created for the vdev_id.conf file (in /etc/zfs/ by
default) to be used in-tree for the test suite
(/var/tmp/zfs/vdev_id.conf).  "./scripts/zfs-helpers.sh -i" needs
to be run before fault tests in the ZTS (to use udev rules in-tree)
