Enhance the stats reported from the Pure Volume Drivers
This change provides some improvements for older scheduler hints and
stats along with a few new stats that can be used for filtering and
goodness functions. These new stats include:
Latency:
usec_per_read_op - Average arrival-to-completion time, measured in
microseconds, for a host read operation.
usec_per_write_op - Average arrival-to-completion time, measured in
microseconds, for a host write operation.
queue_depth - Average number of queued I/O requests.
IOPS:
reads_per_sec - Number of read requests processed per second.
writes_per_sec - Number of write requests processed per second.
Bandwidth
input_per_sec - Number of bytes read per second.
output_per_sec - Number of bytes written per second.
Metadata:
total_hosts - Total number of Purity hosts created.
total_snapshots - Total number of snapshots (includes pending
deletion).
total_pgroups - Total number of Protection Groups (includes
pending deletion).
Note: All of these stats are for the entire array and are not specific
to the Cinder volumes, snapshots, hosts, latency, etc.
As part of the new and improved stats the drivers will respect the
cinder.conf backend “reserved_percentage” option. Previously it was set
to 0.
Last but not least there is a new config option called
“pure_automatic_max_oversubscription_ratio”. This defaults to True, and
when enabled gives the older behavior of automatically calculating the
thin provisioning ratio which was allowed for the backend. If disabled
the driver will now respect the “max_over_subscription_ratio” config
option.

Storwize: Split up __init__ into separate files
This patch is one in a series of patches with the aim to
bring the storwize_svc driver in line with other san based
Cinder drivers.
Currently all the iSCSI and FC code are all together in a single
file. This patch goes into the __init__.py and splits it up into
storwize_svc_iscsi.py, storwize_svc_fc.py, and storwize_svc_common.py.
This new structure is consistent with other san based drivers.
In addition, tests were also updated to reflect the changes listed
above.
Since the driver has been split into two, we need to update how
to enable each new driver. The user now needs to set different
values for volume_driver, as shown below.

XtremIO: fix generic glance cache with XtremIO
* Identify the apropriate error for snapshot limit from the array
and raise the right error to invalidate the cache.
* Add an optional limit to the number of snapshot taken from the
volume representing a cached image
* Add unittest for snapshot limit
vCenter 6.0 added support for a new type of datastore called VVOL
datastore. A VVOL datastore represents a storage container which
is a logical grouping of virtual volumes in an array that supports
VVOL. A virtual disk in a VVOL datastore corresponds to a virtual
volume in the array. Since VVOL datastores are treated like VMFS
or NFS datastores by vCenter APIs, the changes in the VMDK driver
to support VVOL datastores are minimal.
This patch adds the following changes in the VMDK driver to support
VVOL datastores:
* Add VVOL datastore type to the list of allowed datastore types
* Skip VVOL datastore while creating a volume from a preallocated
glance image because it involves replacing the data file of a
temporary virtual disk with the downloaded preallocated image
which VVOL cannot support.

Pass volume_id in request_spec for manage_existing

adds check for it in the unit tests for manage_existing flow.

MagicMock(return_value=None), which isn't actually testing anything

Fix invalid cache image-volume creation
During the volume ref creation in clone_image_volume
we were including a _name_id attribute which is invalid
in the base olso object. The result is silent failure
for a key error. Note that the comments for the column
in the db specifcally state "do not call directly".
The variable is also denoted as private by the _ prefix.
Fix this by just popping the "_name_id' attribute.
In addition there were a number of things that needed
some cleanup:
1. Don't iterate over list of tuples to get K/V for dict
Just use Dict(xxxx)
2. Don't use delete dict.key
This isn't safe, because if the key DNE you'll get a key exception
Instead use pop which is safe if key DNE
3. Add an error message when this fails, because currently the logs
don't give an operation a chance of knowing it failed, let alone
an opportunity to debug it
Finally the cache volume creation is still calling the db
directly and doing a resource create as opposed to
using the new volume object create handler. I went ahead
and converted this to use objects, however that resulted in
breaking two of the volume-->image unit tests that use cinder
as a glance backend.
I've opened bug 1525773 for those issues and added a skip
to the tests in question.
