Deprecate *_multipath_enabled flag for IBM drivers
Deprecate the *_multipath_enabled from the FlashSystem and
Storwize/SVC driver. When enabled, this flag was intended to create
a single mapping between the compute node and the storage device for
FC connections. However, all available storage WWNNs were still being
mapped to the compute node, and instead enabling this flag was
causing a terminate_connection to not cleanup all LUN mappings
(because Nova did not know of all the target_wwns that were actually
mapped). This can be seen by enabling the flag, connecting a volume,
disconnecting the volume and observing the stray LUN mappings under
'/dev/disk/by-path'.
Currently we do not have a way to limit the storage WWNNs which are
mapped during a FC connection, so we will ignore the config to fix
this broken behavior, and then remove the config next release.

Currently each Versioned Object needs to implement its own get_by_id,

Fix swap_volume for case without migration
Fix swap_volume so that even when a volume-migration does not
occur, the volumes don't get stuck in "attaching" and "detaching".
Previously the swap_volume was changed in
https://review.openstack.org/#/c/101932 and
https://review.openstack.org/#/c/101933 to move the final
attach and detach logic to Cinder, however those changes only fix
the migration path. This change calls Cinder's "attach" and "detach"
for the non-migration path to update the volumes' states.

VNX: Fix metadata get overriden issue
Cinder is using 'metadata' or 'volume_metadata' to return

Downstream Fix for Genconfig
This patch adds the opts.py file to the tree as a fix for deployers
that package cinder. The opts.py file is no longer being deleted right
away by generate_sample.sh after the cinder.sample.conf is being
generated.
This patch also introduces a pep8 check to make sure that the opts.py
file is up to date, so that it will catch when new opts get added to
Cinder without the opts.py being updated.
To support the ability to keep and check the opts file a number
of changes were needed in the check_uptodate.sh script as well as
the generate_sample.sh script:
- check_uptodate now takes --checkopts instead of --checkonly
When checkopts is used the opts.py file is generated using the
current code and the generated file is compared to the existing
file. The check fails if there are differences.
- generate_sample now has the --nosamplefile option.
When this option is used, only the opts.py file is generated.
The oslo-config-generator code is skipped so no sample file
is created.
- generate_sample also has some coding style consistency changes.
- Added the 'genopts' option to tox so users can generate
a fresh opts.py without a sample file when necessary.

ip addresses in hp3par_iscsi_ips, find_existing_vluns fails to return

returns the entire list, not just the first vlun.

Fix cinder objects unit test registration
The base test case was extending test code from oslo_versionedobjects
which is bad because (1) it was adding test objects from the o.vo
registry into the cinder object registry and (2) it was extending
internal private test classes from o.vo which are subject to change and
would break cinder.
This cleans up the base test case and object registration to basically
do it the same way that nova does.
It also moves the duplicate _compare() method into the base class and
fixes a bug where db obj fields that were lists were compared
incorrectly against object lists.
This will allow us to verify object version hashes using o.vo's
ObjectVersionChecker fixture in a follow on change without the
extraneous object registrations from o.vo messing with the results.
