Fix 'asert' typo in unit test
The dellscapi unit tests contain two occurences of an
apparent typo, 'mock_get_volume_list.asert_called_once_with'.
Because mock will magically create an 'asert_called_once_with'
method, this typo masks a problem with the test_manage_unmanage
test where the wrong set of arguments is expected.
This commit substitutes 'assert' for 'asert' in these occurences
and fixes up the test_manage_unmanage test.

Fix dynamic import of CONF.volume_api_class
Modifies the import to actually happen when API() is called instead of

This is necessary because CONF.volume_api_class is always evaluated as

module is loaded.

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:

Huawei: Implement v2 replication (managed)
This patch implements the managed side of v2 replication in the
HuaweiDriver. Both Synchronous mode and Asynchronous mode are
supported with Huawei arrays. The volume type need to associate with
the extra spec with 'replication_enabled' equaling to '<is> True', and
'replication_type' equaling to '<in> sync' or '<in> async'. If
'replication_type' is not provided, it will be defaulted to
Asynchronous mode.
What are supported with replication:
1. create volume
2. create volume from snapshot
3. clone a volume
4. create volume from image
5. volume retype
6. volume migration
So far we support a single remote device, and 'cinder.conf' should
configure a replication local backend and a replication remote backend
as follows:
