If, when using a Ceph as a backend for Cinder and Glance, you
create a volume from a Glance image, the request is actioned
in one of two ways; (1) if Glance does not supply sufficient
information to Cinder, a full copy is made of the Glance
image or (2) Ceph uses it's copy-on-write capability to do a
clone. If a full copy is done, the volume is marked as
Bootable=True but if a clone is done it is not.
This does not appear to break nova boot from volume at present
but the status displayed by the cinder client is incorrect.

Update cloned volumes QoS settings.
The SolidFire device inherits all settings (including QoS) from
the parent on a clone. This meant that although we were expecting
QoS to be updated when a clone was issued with a different Volume
Type than the parent volume it was never acted upon.
This change fixes that bug by simply adding the *new* qos settings
to the ModifyVolume call after cloning.
A warning message appears in Cinder logs which state that
inheritance-based rules are deprecated and use default
Brain instead of HttpBrain. It looks like HttpBrain class
doesnt have any difference from Brain class, so changing
all the instances of HttpBrain to Brain shouldn't affect
anything and removes this warning from logs.
Digging further, I found out that the policy engine has
gone through a major rework in Oslo and Nova, and I think
at some point of time in future, we will also be moving
to use the latest policy engine code. In that way of
thinking, I guess this fix is acceptable for now.
Reference: https://review.openstack.org/#/c/14122
Changed the brain from HttpBrain -> Brain, which makes the
warnings in the log disapper. A more comprehensive work will be
to pull the latest policy change code from Oslo.

Fix ownership transfer when cloning with SolidFire
When cloning a volume with SolidFire driver, the owner of
the cloned volume is not set correctly in SolidFire when there is
a transfer of ownership.
This results in inconsistent states where the cloned volume
is owned by the new tenant in Cinder but SolidFire thinks it is still
owned by the original volume's tenant.
This patch adds the newAccountID parameter to all CloneVolume calls.
If the cloned volume is owned by the same tenant, newAccountID will
be set to the same value as the original SolidFire volume. There
will be no change of ownership done by the cloning process in SolidFire.
If the cloned volume should be owned by a different tenant, newAccountID
will be set to the appropriate SolidFire account corresponding
to the new tenant. If the SolidFire account does not exist already,
it will be created.

Make NFS share selection more intelligent.
Make the NFS share selection more intelligent by using a used_ratio

is a hard-cap of maximum "actual" used space, oversub_ratio allows
for oversubscription of the share based upon the apparant-allocated
space for sparse files.
Removed Options: nfs_disk_util
New options added:
* nfs_used_ratio:
Float representation of the maximum allowed usage (e.g. 0.95
calculated by available_space / total_space) before the share
is no longer concidered a valid target. Default: 0.95
* nfs_oversub_ratio:
Float representation of the oversubscriotion ratio allowed when
utilizing sparse files (determined via "du"). This gets
multiplied against the total_capacity before comparing the
apparant space used by the backing volume files. Default
ratio is 1.0 (meaning reserved/allocated space cannot exceed
total space available on the mount).

Update/Publish volume service updates on delete.

The result was that if you exceeded your capacity within the

if you deleted existing volumes until the update was performed and
published.
Since we're updating on on create, there's no reason why we shouldn't
do the same on delete for the applicable volume-service.

alone, but with this change we keep things up to date so the filter scheduler
