Rework Scality SOFS driver to use RemoteFS class
This change is big but the logic is simple. The previous version of
this driver reimplemented most of what is now in the RemoteFS base
class. SOFS stands for Scale Out FileSystem and is based on FUSE, so
it's only natural to leverage the RemoteFS class.

Cinder replication V2
This adds a scaled back replication implementation
that leaves the bulk of the work up to the driver.
We just provide basic admin API methods to do things
like enable/disable and fail-over. Set up and
specification of replication targets for a specific
back end are now intended to be part of the cinder.conf
in the driver section itself.
Replication targets are configured via the cinder.conf
file in their associated driver section. See the devref
doc included in this commit for details on the format.
The next step in configuration is to create a volume-type
with replication info in the extra-specs.
extra-specs = replication=enable, volume_backend_name=foo
This instructs the driver to utilize replication, default is
up to the driver but would suggest single way rep and in the case
of multiple targets, driver could choose or have a default.
If the back end doesn't report replication=enabled in it's stats
updates the scheduler will fail to place the volume due to invalid
host, or no hosts available.
Vendors can easily modify extra-specs or their own config settings
to modify this behavior, any vendor-unique adaptation can be
provided through the use of scoped keys. Suggested examples
will be published in docs.

Update provider_id column on SolidFire init
This patch just implements an init routine to update
the cinder db with provider_id mappings to known/active
volumes on the SolidFire cluster.
Now that we have added a mapping feature in the DB, we need
to go back and populate these columns on an upgrade. It's
also helpful to have this mechanism for internal mappings on
init, that's why it's here as an init routine instead of part
of an upgrade migration or cinder-manager script.

Add ability to update provider_id during init
During the Liberty release we added the ability to store
a provider_id for a volume in the Cinder database. This
simplifies a number of things for back ends when accessing
volumes.
One missing piece here however is that we have no way to
populate this data for existing deployments if/when they
upgrade.
This patch provides a simple solution that issues an update
call to the drivers on host init. It works by fetching a
list of volumes for the specific host, and passes those in
to the driver. The driver can do nothing, or it can go
through and sync up the Cinder ID's with it's internal
ID's and return the provider update info.
Cinder currently doesn't check the existing resource
when user lowers the quota sets. It should have an optional
action that doesn't allow to update the quota of resources
lower than current usage.
This patch adds code to validate the update value of quota and
ensure the value can't be lower than existing resource.
APIImpact
Add an optional boolean argument 'skip_validation' with default value True.
{
"quota_set": {xxxx},
"skip_validation": 'True'/'False'
}
If skip_validation=False and the update value is lower than existing resource,
API will return 400 Bad Request.

Add SolidFire svip to config options
The SolidFire driver uses a simple method of gathering
the Storage Virtual IP, it just queries the Cluster and
asks for the SVIP. This is great almost all the time,
BUT it doesn't take into consideration that the deployer
may be using VLAN's and accessing the cluster from multiple
clouds, or multiple networks.
This patch just adds a config option to specify an SVIP
if the admin has configured VLANs in their environment and
on their cluster. The default behavior is to still use the
global SVIP.

Test whether sample config generation works
Adds --checkonly to tools/config/check_uptodate.sh.
This allows verifying that a configuration file was
generated.
We have had a number of issues introduced which
have caused config file generation to fail since we
removed the sample config file check in the gate.
This does not add back checks to ensure that the file
has been updated, it only checks to ensure that it is
still possible to update the sample file.
Adding optional dependency tracking would be nice,
but Cinder is not yet in a place to do this.
- Cinder supports tox 1.6 (minversion in tox.ini)
- This functionality does not work on 1.6, requires 1.7. Tox
fails to build a test environment if using tox 1.6.
- We have decided we can't move to tox 1.7 for now.

Capacity filter uses free_virtual capacity to filter out a host if
thin provisioning is enabled and over-subscription ratio is less
than or equal to max_oversubscription_ratio. The current formula

Add volume migration support for Huawei driver
If the target host and the original volume are on the same array,

of a particular project from one vCenter datastore to another.
