ZFSSA iSCSI vol create fails with vol type option

Vol create with volume-type option is not working since
volume_backend_name contains the class name as
predefined string. No matter what was specified in cinder.conf
as volume_backend_name, volume creation failed.
Multi-backend option and using extra specs to create custom volumes
won't work.
The fix is to look whether volume_backend_name is part of the
configuration or falls into the class name in case there is
no backend name.

ZFSSA iSCSI driver cannot add multple initiators to a group

All initiators defined in zfssa_initiator property would be
added to the group.
Also fixed some typos related to initiators error messages.

Fix race condition in ISCSIConnector _disconnect_volume_multipath_iscsi

This is a similar issue as seen in 
https://bugs.launchpad.net/cinder/+bug/1375382

The list of devices returned by driver.get_all_block_devices() in
_disconnect_volume_multipath_iscsi will potentially contain broken 
symlinks as the SCSI devices have been deleted from calling
self._linuxscsi.remove_multipath_device(device_realpath) right before
_disconnect_volume_multipath_iscsi but the udev rule for the symlink 
may not yet have completed.

Adding in a check to os.path.exists() will ensure that we will not 
consider the broken symlinks as an “in use” device.

Deprecate / obsolete NetApp volume extra specs

The NetApp Data ONTAP (Cluster-mode) NFS & iSCSI drivers for Juno support
the Cinder pools feature, but the drivers are reporting two qualified
extra specs that must be converted to unqualified extra specs in order to
be used by the Cinder scheduler's capability filter. Furthermore, there
are four extra specs that must be deprecated due to having the pools
feature.  Warnings will be logged during volume creation if any of the
obsolete or deprecated extra specs are seen in the volume type.

Handle eqlx SSH connection close on abort.

EqualLogic array CLI operation timeout causes the
SSH thread to be aborted. This would cause SSH
sessions to be orphaned and hit a max connection
limit on the array. This fix catches these aborts
and makes sure the connection is closed.

Clarify InvalidInput exception when the size is missing

In the case where size is None, the exception message
'Volume size  must be an integer...' is misleading.

Refuse invalid qcow2 backing files

Don't allow qcow2 files that are pointing to backing files outside of:

Windows SMBFS: Handle volume_name in _qemu_img_info

The volume_name is now parsed to the _qemu_img_info wrapper. As
this method is not prone to security issues because this driver
does not support raw images (at least not yet), we don't have to
perform any checks on the backing image file path.

Thus, this method simply ignores this argument that will be parsed
by the base class methods.
