Fixes EUCA-3782 by removeing stale /var/lib/iscsi/node/ entries
Fixes EUCA-3119 : Creates volumes with permissions of eucalyptus:eucalyptus instead of root:root
Fixes EUCA-3119 : Creates volumes with permissions of eucalyptus:eucalyptus instead of root:root
Fixes SAN-58

Netapp volume options are set after a volume is created on the SAN.
If these options cannot be applied for some reason the volume is marked failed in eucalyptus and deleted from the SAN.
Re-enables the SC reload capabilities for OverlayManager on service start. Fixes EUCA-5040.

During SC startup in OverlayManager it will scan the DB and attempt to re-export any volumes
that were exported (had iscsi targets) on last shutdown. The decision is made based on the
presence of a loopback device name in the DB. The reload process will restore loopbacks,
assign new ones if the previous is taken by another resource, and ensure that LVM LVs are
enabled and iSCSI targets reconstructed. If volume is already exported (i.e. just a service
restart instead of a machine reboot), then the process cleanly leaves existing resources
untouched.

Also adds many INFO level log messages to track process during startup. Grep for 'SC Reload'
in the cloud-output.log to see the process.

Removed call to udev trigger in get_iscsi_device(). Fixes EUCA-4627

Originally called udev trigger to fix a problem with permissions not
being set on mounted devices, but the trigger did not solve the problem
and was never removed. Removed it now as it can cause unintended
side-effects.
