NetApp fix free space as zero during 1st vol stats update
NetApp clustered ontap drivers report space as zero
till first 60 seconds of driver start. This is causing
discomfort for some performance sensitive deployements.
This was due to async nature of the NetApp stats collection job.
Job is changed to sync at driver start to improve customer
experience.

Subclass vendor specific exceptions.
Up until now drivers have been able to define their
own custom exception classes. In most cases these are
inherited from either a native python exception class
or at best the base cinder exception class.
The problem with this is that it makes it very difficult
for higher layers (such as volume manager) to do any intelligent
exception handling and the base Cinder.exception class is too broad.
This change takes the first step in cleaning this up. We create
new exception classes for all drivers to inherit from:
VolumeDriverException
VolumeBackendAPIException
BackupDriverException
This still allows the freedom to create custom exceptions for a
particular driver, however it also gives us a common exception
class to catch and check in higher levels. Further refinement
and standardization will be helpful going forward but this
should give us a good start.

GlusterFS: Synchronize operations that manipulate qcow2 data

Fail when image is bigger than the volume
When creating a new volume from a qcow2 image stored in glance, we will
be given the physical size of the image instead of the virtual size.
Most drivers will convert that image to raw after downloading for
resizing it to the requested volume size afterwards.
If the virtual size of the image is bigger than the requested one, the
resulting volume might end up being unusable after the resize even
though the creation went good.
This patch will make the volume creation fail if the virtual size of
the image exceeds the one of the requested volume.

Remove lvm-thin pool_size config option
The pool_size config option when using thin LVM
is never actually checked/honored. It's also unlikely
that users will want to do something other than use the
entire VG for their thin pool.
Rather than have the unused option going forward let's
remove it from the config and just go with the default
behavior of utilizing the entire Cinder VG.
For folks that would like to only use a portion of the
VG for some reason, they can do an lvcreate pool on their
own (just like we have them do for the VG itself) and get
the same flexibility that way.
This is done simply by:
lvcreate -T -L ${size} ${vg-name}/${vg_name}-pool
