Port IBM storewize_svc driver to Python 3
Change default preferred node in
StorwizeSVCDriver.initialize_connection(). For fiber channel without
multipath, pick the first node from the list of sorted nodes, to have
a determinist preferred node. The list of nodes is created indirectly
using list(set(nodes)) which doesn't have a determinist order. On
Python 3, the hash function is randomized, and so list(set()) has an
unknown order.
A similar change was done for volume throttling in the change
Icf7141f772397c7ac08f0f1e21ad74cb86a06351 to port the code
to Python 3.
Other changes:
* Use assertSetEqual() in test_storwize_svc to compare
initiator_target_map, because conn_wwpns has a random order on
Python 3.
* StorwizeSVCDriver._check_volume_copy_ops(): replace dict.items()
with list(dict.items()) to iterate on items. On Python 3,
dict.items() now returns a view instead of a copy. The loop
modifies the dictionary and a dict must not be modified while
iterating on it, we really need a copy of items.
* StorwizeHelpers: replace a/b with a//b to use integer division on
Python 3.
* tests-py3.txt: add cinder.tests.unit.test_storwize_svc

XtremIO fix attach readonly bug
* Remove the access_mode from connection_info and let the manager decide
on the access mode.
* add a test to make sure access_mode won't be added in the future
The create method of consistency group API requires a list of
volume type ids; volumes belonging to only these types can be added
to the consistency group. The get method of the consistency group API
does not, however, return the volume type id information.
Horizon needs this value for its "Add volumes to consistency group"
panel so that it can filter the "available volumes" list to only
show volumes that match the volume type associated with the consistency
group.
This was fixed by propagating the volume type id information in
the api layer (this information is stored in the db, it just wasn't
being propagated).

The get method of the consistency group API now returns the volume
type ids information.

Fix the bug of OSError when convert image
When I try to convert a image use image_utils.convert_image() method,
an error occurred like this :
'''
OSError: [Errno 2] No such file or directory:
'sheepdog:10.133.17.61:7000:volume-a0a70f9b-a50e-4369-885f-c41a894c9fe5'
'''
The reason is that in some cluster storage systems, like
ceph/sheepdog, QEMU can access an image directly via their private
protocol, and there’s no need to map an image as a block device on
the host. In this case, the qemu-img convert command may like:
#qemu-img convert -O raw sheepdog:Ip:port:image_name temp_file
#qemu-img convert -O raw rbd:pool_name/image_name temp_file
The source path may be 'sheepdog:Ip:port:image_name' or
'rbd:pool_name/image_name', it doesn't exist in OS. So, when it runs
the os.stat(source) in image_utils.convert_image(source,dest,out_format)
method, an OSError would be raised.
We can use qemu_img_info method instead to resolve this problem, because
the 'qemu-img info' command can always get the image size info which has
support qemu-img tool. Here we capture a ValueError just in case, but it
only need to give a warning message, because the image has been successfully
converted.

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.

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.
