Rtstool sets wrong exception message on save
Rtstool does not properly set the message on the RtstoolError exception
on the save_to_file method (save operation) because it's passing
formatting arguments as if it were a LOG call instead of formatting
those same arguments with
%.
There are 2 cases where this can happen, when saving to the default
location on a system that has no target.service installed and the
creation of the default directory fails, and when saving the file
actually fails.
This patch properly formats the message before passing it to the
instantiation of RtstoolError exception.

Scaling backup service
Currently the cinder backup service is tightly coupled to the cinder
volume service in ways that prevent scaling out backup services
horizontally across multiple physical nodes.
This patch is to loosen this coupling to enable backup processes
to run on multiple nodes without having to be colocated with volume
services.
The following works are not included in this patch:
1. Remote attach snapshot.
2. Vendor specific work.
3. Remove current backup_volume in driver.
4. Rolling upgrades.

Add restore_volume_id in backup
This patch is to add restore_volume_id in backup object.
When restoring a volume from a backup, it saves the
volume in backup object.
Currently volume service and backup service are in same host.
When backup service starts, it does cleanup tasks on both
backups and volumes on current host.
But with bp scalable-backup-service, backup service and
volume services can run on different hosts. When doing cleanup
tasks, we need to find out backing-up and restoring volumes
related to the backups on current host. Backing-up volumes can
be found with field backup.volume_id. Restoring volumes are found
by new field backup.restore_volume_id.

Fix 'asert' typo in unit test
The dellscapi unit tests contain two occurences of an

Because mock will magically create an 'asert_called_once_with'

This commit substitutes 'assert' for 'asert' in these occurences

Remove Cisco FC Zone Manager Driver
After many attempts to get a Cisco CI running to validate the Cisco FCZM
driver over a few releases there is still no official third party CI

We can't include drivers that do not have test coverage and no report of
whether it is working as expected. Until there is test coverage, we will
need to remove this driver due to lack of CI.

Add variable QoS to NetApp cDOT drivers
Most QoS implementations involve fixed limits, such as maxIOPS
or maxBPS. But there are clouds that offer QoS limits that are
partly based on capacity of the underlying resource. This commit
adds two new QoS flags to the NetApp cDOT drivers, maxIOPSperGiB
and maxBPSperGiB, which implement this capability. A light
refactor of the snapshot delete paths was required to separate
those from the volume delete paths, since only the latter should
involve the QoS logic.

Storwize: Implement v2 replication
Storwize supports three major types for volume replications:
split IO, global mirror and metro mirror.
This patch is dedicated to implement the replication for
the modes of global mirror and metro mirror. Mirror
establishes a Global/Metro Mirror relationship between
two volumes of equal size. The volumes in a Mirror
relationship are referred to as the primary volume and
the replica volume. The replication_mode in
replication_device must be set to global or metro.
The volume type needs to associate with the extra spec
with 'replication_enabled' equaling to "<is> True", and
'replication_type' equaling to '<in> global' or '<in>
metro'.
What is supported with replication:
* create volume
* create volume from snapshot
* clone a volume
When a volume is created and replication is enabled, the
replica volume is also created on the back-end enabled
for replicas.
What is not supported with replication yet:
* volume migration
* volume retype
The replica volume will not be created or moved after migration
or retype of a replicated volume. Admins should be aware,
when migrating or retyping a volume to a type with replication
enabled, that the replica will not be automatically created.
The replication can be configured via either multi-backend
on one cinder volume node, or on separate cinder volume
nodes.
Options to be put in cinder.conf, where the primary back-end
is located:
