ZFSSA driver to return project 'available' space
This fix allows the iSCSI driver to return the 'available' space

accurate in cases when storage is not thin provisioned.

Sync volume versionedobject to ORM
The following patch syncs the volume object to match the
ORM. More specifically, it adds metadata, admin_metdata,
volume_attachment, and volume_type to the volume object.
These fields are required to convert cinder internals to
use volume versionedobject. It was originally part of
a large patch, but is broken up to make reviews more
bearable.
When importing backup metadata only required fields were being imported,
and all other fields were being ignored.
This led to some serious problems when importing backups back, since
you would lose not only the original Volume ID, but also relevant parent
id information needed to restore incremental backups.
This patch fixes this by importing everything back and creating backup
records with the right ID.

Add support for file I/O volume migration
This patch changes the generic volume migration logic to support
non-attachable volumes. Non-attachable refers to volume drivers that do
not support attachment via the typical iSCSI or similar protocols where
a block device is made available on the host machine. Device drivers
such as RBD make volumes available to cinder via a file handle that
proxies read() and write() calls to the Ceph cluster.
This patch improves the generic migration logic to determine whether a
migration operation can proceed with dd using block device paths or file
operations on handles returned from the os-brick connectors.
Changes to the RBD driver are included to correctly rename the target
volume during the completion phase of a successful migration.
It appears there is still some work to be done for attached in-use
volume migration for certain configurations. Successful tests were seen
for:
LVM to LVM (available and in-use)
LVM to/from NFS (available and in-use)
LVM to/from Ceph (available)
Ceph to LVM (in-use)
NFS to/from Ceph (available)
Ceph to NFS (in-use)
Failures were seen (due to Nova) for the following:
LVM to Ceph (in-use)
NFS to Ceph (in-use)

Add debug logging before attaching volume in driver
It'd be helpful to log the volume/instance/mount/host
information in attach_volume before calling the volume
driver to do the attachment to know we have the right
values.
Deleting volumes in CloudByte Storage is an asynchronous process.
So, the driver needs to wait till the job/process is completed.
The driver uses the jobid in a wait loop for a configured interval
of time, till the volume deletion is completed.
Efficient volume copy for generic volume migration
Currently Cinder uses dd command for data copy of volume migration,
but the copy always copy full blocks even if the source data contains
many null and zero blocks. The dd command has an option conv=sparse
to skip null or zero blocks for more efficient data copy.
However, if the destination volume is not zero cleared beforehand,
we should copy full block from source to dest volume to cleanup dest
volume in order to avoid security issue.
If the volume pre-initilization(zero cleared) is ensured beforehand,
we can skip copy of null and zero blocks to destination volume by
using sparse copy.
In order to use this option properly, we have to check
sparse_copy_volume capability for destination backend driver via
RPC API before volume copy.
This patch also adds sparse_copy_volume capability flag into volume
stats of LVM and NFS drivers to enable efficient copy for these
backends.

Volume status management during migration
This patch proposes a new implementation for the status and
the migration_status for volumes.
* The initial migration_status is None, meaning no migration has been
done; Migration_status 'error' means the previous migration failed.
Migration_status 'success' means the previous migration succeeded.
* If the key 'lock_volume' is set to True from the request, the volume
status should be set to 'maintenance' during migration and goes
back to its original status after migration. Otherwise, if the
key 'lock_volume' is set to False, the volume status will remain the
same as its original status. The default value for lock_volume is
False and it applies to the available volume.
* From the REST's perspectives, all the create, update and delete
actions are not allowed if the volume is in 'maintenance', because
it means the volume is out of service. If it is not in maintenance
mode, the migration can be interrupted if other requests are
issued, e.g. attach. For the termination of migration, another
patch will target to resolve it.
DocImpact
APIImpact The key 'lock_volume' has been added into the API,
telling the volume to change the status to 'maintenance' or not.
The migration_status has been added into results returned
from volume list command, if the request is from an admin.

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.
This patch adds a base framework of capabilities reporting
feature. The get_capabilities RPC API returns dictionary
which is consisted of two parts.
First part includes static backend capabilities which are
obtained by get_volume_stats(). Second part is properties
which includes parameters correspond to extra specs.
This properties part is consisted of cinder standard
capabilities and vendor unique properties. These properties
are created via these two methods.
Since _init_standard_capabilities() only exposes cinder
standard capabilities into the properties dictionary,
each backend driver needs to expose their own properties
by overriding _init_vendor_properties().

Dell SC: init_volume stale volume info fix
In init_volume the volume information becomes stale after the volume

The unmap function was testing for the volume being active. This

mappings but not impossible. This check has been removed.
Removed LOG.error from _find_mapping_profiles as the API returning
an error is fine if the volume is inactive. Plus we were not failing
