Add cinder backup driver for Google Cloud Storage
Implement cinder backup driver for Google Cloud Storage.
It supports:
- creating backup which is stored on Google Cloud Storage
- restoring backup from Google cloud storage
- incremental backup
- independent of any volume backend

Activate sparse copy for Netapp
Activating sparse copy of files since using
"volume migration" or "retype" the size of the resulting
file is larger than before. Due to the reason that the
sparse blocks in the file are copied over completely. This
is inefficient performance wise and wastes space on the
storage itself.

Add Fujitsu ETERNUS DX Volume Driver (FC part)
As I explained in my blueprint,
this patch completes Fujitsu ETERNUS DX Volume Driver.
Fujitsu ETERNUS DX Volume Driver consists of two parts, iSCSI and FC.
The iSCSI part [1] had been reviewed and
thanks to the nice reviews, it's merged.
The iSCSI and FC parts have a lot of common codes,
and all the common codes are included in the iSCSI part.

Python 3: Replace reduce and xrange with six.moves
1. Builtin function 'reduce' in Python 2 has been moved to standard
library module in Python 3 [1]. To make code compatible, replaced
reduce(expr) with six.moves.reduce(expr).
2. xrange is renamed to range in Python 3, replaced it with
six.moves.range
3. Added __bool__() method in FeatureState class to make it python 3
compatible because Python 3 calls the __bool__() method instead of
__nonzero__ when evaluating an instance in a boolean context.
4. Added this test case to tests-py3.txt.
In the case where a LUN is extended beyond it's supported geometry,
a new LUN must be created and only the used blocks should be copied
to the new LUN. Currently, we do not pass the block count, source
block, and destination block information. This causes the extend to
fail.

Fix ChunkedBackupDriver _create_container
Current _create_container method in ChunkedBackupDriver is not behaving
as expected.
According to update_container_name docstring the method should return
None if the container name that comes in to the driver is to be used,
but code was using backup_default_container instead.
Also, if None is returned by update_container_name the logging will
report that it will be using None instead of the name that it will be
really using.
If update_container_name returns the same value we already have in the
DB, driver will unnecessarily update the DB.

Handling Invalid argument iflag=direct in dd
During volume/snapshot create/delete operations,
dd command is used to clear contents of disk.
Before invoking dd, it is checked if iflag=direct
supports dd or not by executing dd command with
iflag=direct and if=/dev/zero combination.
But this always results in invalid argument
error.
Handling for this argument is done to eliminate
unnecessary call to dd command when it is used

Currently the existence of 'mount.nfs' is checked with a

Enable consisgroups in SolidFire driver
This patch enables Consistency Group support in the SolidFire driver.
SolidFire group snapshots are what is used to provide consistent

A variety of helpers were used to wrap the API requests, meanwhile
other helpers were utilized to jump through the necessary hoops to
adopt the SolidFire API/group snapshots for use in consistency groups.
Because the SolidFire array does not create logical groupings of
volumes as consistency groups, there are a lot of no-ops used to
satisfy the necessary Cinder functions as specified in driver.py.
In-line comments attempt to clarify this. In short, a lot of searching
is needed to create consistency groups on the fly per request.
