Use Unique SCST Group names in SCST cinder helper driver.
Currently, while setting up GROUPS under targets in scst.conf,
we are using the Initiator IQN as the group name. When we have
multiple targets and we want to connect LUN's from these multiple
targets to the same initiator, we are using the same GROUP name in
all the Target sections.
It would be good to provide a unique group name by prepending the
GROUP name with the target name. So the GROUP name will be
"Target name+Initiator IQN".

Remove warnings for long vgs and lvs calls
We put some warning statements in a while back for
lvs and vgs commands that lasted more than 60 seconds
so we could easily query issues in the gate.
Since then we've made a number of changes to improve our
LVM interactions including the use of an LVM conf file with
a filter for only the VG's Cinder uses.
There's one issue remaining however where during the instance
rescue test in Nova where LVM get's stuck trying to open
devices that no longer exist. Part of this I think is due
to some manipulation that Nova/KVM does on the attached volume
when the test is run, but also the rescue process in Nova
uses LVM volumes as well and does some moving around and mounting
of devices.
The result is that LVM calls can take quite a while
(greater than 100 seconds) to complete during the rescue process.
This doesn't result in any failures, just that the rescue process
slows things down dramatically and is a pretty heavy process.
Also, the newer versions of process utils include completion
timing in the logs so we don't really need this any longer eve
to query timings and get info.
This patch removes those log statements, and proposes we
document somewhere that rescue operations on a setup that
includes c-vol service and nova-compute service on the same
node will temporarily impact LVM performance.

Refactoring for export functions in Target object
Currently, export functions such as create_export() are implemented
in individual Target code, but most of them are same and these are
common features in each target.
This patch moves these methods to parent ISCSITarget class to
commonalize and each Target simply inherit these methods from parent
class. As a result of this change, LioAdm can inherit ISCSITarget
class directly instead of inheriting TgtAdm class.
This simplifies dependency of targets and improves maintainability.
By refactoring these methods, this patch also fixes following issues.
(a) Fix bug #1410566
After transitioning to the new driver and target model, iscsi_targets
is not added to the table during create_export() phase.
However, remove_export() in LIO Target is still reffering empty
iscsi_targets table. This causes NotFound exception and remove_export()
skips to do remove_iscsi_target().
As a result, iscsi target is not removed and the target continues to
grab the volume(logical volume) as an in-use status.
This patch fix the problem.
(b) Re-export a volume with CHAP
Current Tgt Target recreate iscsi target without CHAP during
ensure_export() even if the volume is exported with CHAP previously.
This patch changes this bahaviour to recreate iscsi target using
previous CHAP which is stored in volume file on state_path dir.
