Refactor PureISCSIDriver into base and iSCSI classes.
This adds in a new class called PureBaseVolumeDriver that contains
all of the generic shared methods that utilize the management REST API.
The PureISCSIDriver now inherits from the base driver and implements
the functionality required for iSCSI hosts/initiators.
As part of this we’ve cleaned up some of the logging where it would
previously have hard coded the drivers class name in it, and moved some
static non-class helper methods into the base class.
These changes will ease future work to add additional drivers or split
them into separate files.

Fix cinder concurrency issues on rtstool
Since there's no synchronized access to configfs in rtslib it can happen
that rtstool or rtslib access an element that no longer exists because
it has been removed just in the middle of a loop by another Cinder

This results in quite a different number of exceptions:
- .dump()
- KeyError
- IOError
- RTSLibError on storage_object

Use SolidFire snapshots for Cinder snapshots
This patch just replaces the use of clones on the SolidFire
backend for SolidFire Snapshot objects. This isn't necessarily
an issue, but it is important necessary to do things like
consistency group snaps.
Note, that we have to keep compatability for things like
create_from_snapshot where the system may have clones that
were used for snapshots prior to updating the driver.
While we're here, we also removed the logging calls in the test

debug messages like "entering/leaving". More cleanup work
can be done to logs but should be in their own patch.

Fix capacity filter to allow oversubscription
Currently the capacity filter does not allow oversubscrition
if the free physical capacity is less than the new volume size.
This was based on the assumption that a new thinly provisioned
volume will be consumed right away. This assumption does not
allow us to take full advantage of thin provisioning.
The fix is to allow oversubscription if thin provisioning is
supported and max_over_subscription_ratio is greater than or
equal to 1. The free physical capacity will not be used to
compare with the new volume size for a backend that supports
oversubscription in thin provisioning. The oversubscription
ratio and virtual free capacity will still be used to decide
whether a backend can be chosen for thin provisioning.

Add standard QoS spec support to cDOT drivers
This commit adds support for standard cinder QoS specs to
NetApp cDOT drivers, alongside our pre-existing support for
externally provisioned QoS policy groups via qualified
extra specs.
Previously, the logic to calculate the LUN ID only considered a single attached
host. Because multiple hosts can be attached to a LUN, the logic needs to
consider multiple hosts. This patchset proposes to choose non-conflicting
LUN IDs across the whole array. This patch first checks for an empty LUN ID
across the array. If it doesn't find one, then it looks for the least used
LUN ID across the whole array.
The value of MAX_LUNS_PER_HOST has been changed here as the range function
iterates from 0 to n-1 LUN IDs. With Eseries backend, a maximum of 256 LUN_IDS
are supported, thus a value of 256 MAX_LUNS_PER_HOST is required.
