Storwize: add config option to control flash copy rate
When creating a flash copy of a vdisk during a clone
or a snapshot operation the svcinfo mkfcmap operation
allows the specification of a copy rate for the flash copy.
The default copy rate is 50. The issue with 50 is it not
always an acceptable default copy rate for a particular
operator. Some operators want it slower but some want to
increase the default copy rate.
Adding a configuration option storwize_svc_flashcopy_rate
to allow an operator to specify the default flash copy
rate to be used when starting a vdisk flash copy on a
clone or snapshot operation.

Remove db access from 3PAR and LH cg functions
The HP 3PAR and HP LeftHand drivers no longer need to access the db in

* delete_consistencygroup
* create_cgsnapshot
* delete_cgsnapshot
This patch removes all db access at the driver level for both 3PAR and
LeftHand drivers.

Additional VAG support for SolidFire
This patch removes volumes from volume access groups, and potentially volume
access groups, when a connection is terminated. When the previously added
'sf_enable_vag' option is enabled and a volume connection is terminated, if the
volume was part of a VAG then the volume is removed from the VAG. If the volume
is the only remaining volume in the VAG then the VAG is also removed.

VNX: Fix metadata get overriden issue
Cinder is using 'metadata' or 'volume_metadata' to return
volume metadata since versionedobjects is not fully merged,
so VNX could not get the correct existing
metadata, only append VNX specific metadata so existing
metadata get overridden.
In this fix, VNX will first try 'volume_metadata' if not exists,
try 'metadata' when getting metadata.

Added VAG support to SolidFire
This patch adds VAG support to the SolidFire driver.
This includes a new config option 'sf_enable_vag'.
The driver creates a new VAG based on initiator name during
connection initialization.
By default VAG support is disabled. When enabled, the driver uses both
CHAP and VAG authentication.
A superclass exception (error) is being handled before
a sub class exception(SSLError) which is making the latter
exception clause unreachable. Corrected the order of these
exception clauses.

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.

When 3PAR iSCSI driver is configured for multipath, with multiple
ip addresses in hp3par_iscsi_ips, find_existing_vluns fails to return
more than 1 vlun. The problem with this is that every time
initialize_connection is called, the driver will not find the vlun it expects
to be there, and then it will create a new one.
This patch removes the break inside of find_existing_vluns, so that it
returns the entire list, not just the first vlun.

Test for object version hash changes
Use the ObjectVersionChecker fixture from oslo.versionedobjects to check
when Cinder's registered objects have a change (new remotable method,
new field, etc) that require a version bump.
Fixes some registration problems along the way:
1. CinderObject doesn't need to be registered.
2. TestObject should be registered where it's used, not globally.
Removes deps=requirements.txt from tox.ini since it's not necessary and
prevents us from pip installing oslo.versionedobjects[fixtures].

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.
