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.
Reverts the changes to cinder/volume/manager.py added in
commit b868ae707f9ecbe254101e21d9d7ffa0b05b17d1 as calling
remove_export in terminate_connection causes Nova live

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.

The fix for bug 1356368 hard-coded a policy check (same as

Note that before commit 0505bb268942534ad5d6ecd5e34a4d9b0e7f5c04,
DB query volume_get() actually acted as the policy checker for
volume:get, and it raised VolumeNotFound if context.project_id didn't

Rewrite ionice command filter using ChainingRegExpFilter
Currently, the ionice command prepended to a dd command is allowed by three
rootwrap RegExpFilter's that cover 3 arguments patterns. However, this
doesn't support if either 'iflag=direct' or 'oflag=direct' is omitted.
Because of this problem, deletion of volumes may fail if volume_clear_ionice

This commit fixes this problem by replacing the filters with
ChainingRegExpFilter's, which allow to execute ionice to be combined with the
other allowed commands, including 'dd'.
Originally '-c[0-3]( -n[0-7])?' was allowed as an ionice option, but it is
invalid to specify -n[0-7] in a single option (for example, when '-c2 -n7'
is specified, ionice causes an error "invalid class argument: '2 -n7'").
In this patch, 2 filters are provided to cover the case only with -c option
and the case with both -c and -n options.
