Add QoS support to IBM Storwize driver
IBM Storwize driver can be enabled with QoS support by setting the parameter
I/O throttling rate, which caps the amount of I/O.
This patch add the QoS configuration to the methods of create_volume,
create_volume_from_snapshot, create_cloned_volume and retype.
The QoS for IBM Storwize storage can be configured in 3 ways:
* Add the key "qos:IOThrottling" into a QoS spec and associate this QoS
spec with a volume type.
* Add the key "qos:IOThrottling" into the extra spec of a volume type.
* Add a metadata with the key "qos:IOThrottling".

Consistency Groups
This patch enables Consistency Groups support in Cinder.
It will be implemented for snapshots for CGs in phase 1.
Design
------------------------------------------------
The workflow is as follows:
1) Create a CG, specifying all volume types that can be supported by this
CG. The scheduler chooses a backend that supports all specified volume types.
The CG will be empty when it is first created. Backend needs to report
consistencygroup_support = True. Volume type can have the following in
extra specs: {'capabilities:consistencygroup_support': '<is> True'}.
If consistencygroup_support is not in volume type extra specs, it will be
added to filter_properties by the scheduler to make sure that the scheduler
will select the backend which reports consistency group support capability.
This will add a cgsnapshot entry in the new cgsnapshots table, create
snapshot for each volume in the CG, and add a cgsnapshot_id foreign key
in each newly created snapshot entry in the db.

Add support in Cinder for volume replication - driver approach
This is take #2 for managing replicaiton in Cinder.
This patch provides the foundation in Cinder to make volume
replication available to the cloud admin. It makes Cinder aware
of volume replicas, and allows the cloud admin to define storage
policies (volume types) that will enable replication.
In this version Cinder delegates most the work on replication
to the driver itself.
This includes:
1. Driver exposes replication capabilities via volume type convention.
2. Extend volume table to include columns to support replicaion.
3. Create replicas in the driver, making it transparant to Cinder.
4. Volume manager code to handle API, updates to create_volume to
support creating test replicas.
5. Driver methods to expose per replication functions
Cinder-specs available at https://review.openstack.org/#/c/98308/
Volume replication use-case: Simplified disaster recovery
The OpenStack cloud is deployed across two metro distance data centers.
Storage backends are available in both data ceneters. The backends
are managed by either a single Cinder host or two, depending on the
storage backend requirements.
Storage admin configures the Cinder volume driver to support
replication.
Cloud admin creates a volume type "replicated" with extra-specs:
capabilities:replication="<is> True"
Every volume created in type "replicated" has a copy on both
backends.
In case of data center failure in first data center, the cloud admin
promotes the replica, and redeploy the VMs - they will now run on
a host in the secondary data center using the storage on the
secondary data center.
