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.

Honor volume:get policy
The fix for bug 1356368 hard-coded a policy check (same as
rule:admin_or_owner) for volume:get. While in most cases this is
what people want, it'd be good we honor policy setting.
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
match volume['project_id']. The check_policy() in volume:get didn't
get a chance to raise PolicyNotAuthorized exception. So in this
change we keep the same behavor.

The extended snapshots extension makes a separate db request for

Mock out image source file in image_utils tests
Change 202ebc2d987c86984ba9cf8e8e36c32899baaa3b
added some metrics gathering around time to fetch
and convert images. To do this it uses os.stat,
and when it was written and tested on Linux everything
was cool.
Turns out however there were a few more methods that needed
mocks for the stat command. This patch adds them.
Also, it was pointed out that for this specific set of tests
we don't actually need to set the class stat_results, mock
will just work for us here since we're not checking an explicit
value. So this patch also removes those class decl's from
previous methods as they're not needed and we should keep
things consistent.

Add iSCSI Target objects as independent objects

TgtAdm and LIO drivers have been tested with the new LVM object.
All existing drivers are still able to be specified and use the
same objects and code-path they were using previously. New
connector objects are only used when specifying the new driver.
Next step will be mapping current ref LVM driver to the new
LVM object and target model and working on the unit-tests.
After that mark the "old" methods and objects as deprecated
and we can then begin working on some other improvements.

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
is set, as 'iflag=direct' is omitted.
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.
