Implement the update_migrated_volume for the drivers
This patch implements update_migrated_volume for LVM, Storwize
and updates Dell, StorPool and Infortrend drivers accordingly. It
makes sure that after a successful volume migration, the cinder
volume name(id) is the same as the backend volume name(id). Other
back-end drivers can take this patch as a reference to implement
update_migrated_volume.
PS: Not applicable to multi-attached volumes, since we need to wait
until the multi-attach lands in Nova.
This patch also adds a unit test for the StorPool driver's
update_migrated_volume() implementation.

Fix cinder.conf.sample generation
Introduction of the hp_xp driver broke cinder.conf.sample generation due to
the way the driver was registering the configuration items. Originally the
options were being included into the FC driver file and registered there.
When the config generator found the options in the separate hp_xp_opts.py
file it did not know what group to include the options in since they were
not registered at all.
This fix moves registration of the options to the hp_xp_opts.py file so
that the config generation will work. Since cfg.CONF is a global, the
hp_xp driver will still have access to the options in there after they are
set by importing the opts file. An additional problem that was uncovered
when creating this fix is the fact that the old config generator we are
using from oslo-incubator doesn't support using cfg.Opt. To temporarily
workaround this I have changed the cfg.Opts to be cfg.IntOpts or
cfg.ListOpts(as appropriate) and documented the valid values for those
options.
The last change that was necessary was to add config values for several of
the options in cinder/tests.py as the options were marked as required by
the driver. If values were not set this caused oslo config to error out
reporting that they values needed to be set.

Cinder volume logs sometimes show this error
NetApp API failed. Reason - 13114:
No actual-pathname for 10.1.0.9:/vol/whatever

The issue is due to our Cinder driver passing the
