Implements new 'bootable' option for manage existing volume.
A 'bootable' option (defaults to False) can be passed as part of
the HTTP POST request to manage an existing volume. This is
passed into the database when the volume is created.
Also changes all drivers to use the more agnostic keys
'source-name' or 'source-id' when specifying
which existing volume to manage. This change is to support the
cinderclient change in https://review.openstack.org/#/c/76216/
to make it easier for CLI users to manage existing volumes
without having to know the implementation-specifics of the driver.
Due to fact that when uploading a volume to an image the file is
opened in text mode and the different line endings style on
windows glance client won't be able to upload the desired file.
The solutions is to simply open the file in binary mode when
performing this action.

Add additional explicit imports of _ where needed

Add affinity/anti-affinity filters
Cinder has done a good job hiding the details of storage backends from end
users by using volume types. However there are use cases where users who
build their application on top of volumes would like to be able to 'choose'
where a volume be created on. How can Cinder provide such capability without
hurting the simplicity we have been keeping? Affinity/anti-affinity is one
of the flexibility we can provide without exposing details to backends.
The term affinity/anti-affinity here is to to describe the relationship
between two sets of volumes in terms of location. To limit the scope, we
describe one volume is affinity with the other one only when they reside in
the same volume back-end (this notion can be extended to volume pools if
volume pool support lands in Cinder); on the contrary, 'anti-affinity'
relation between two sets of volumes simply implies they are on different
Cinder back-ends (pools).
This affinity/anti-affinity filter filters Cinder backend based on hint
specified by end user. The hint expresses the affinity or anti-affinity
relation between new volumes and existing volume(s). This allows end
users to provide hints like 'please put this volume to a place that is
different from where Volume-XYZ resides in'.
This change adds two new filters to Cinder - SameBackendFilter and
DifferentBackendFilter. These two filters will look at the scheduler hint
provided by end users (via scheduler hint extension) and filter backends by
checking the 'host' of old and new volumes see if a backend meets the
requirement (being on the same backend as existing volume or not being on
the same backend(s) as existing volume(s)).
For example:
Volume A is on 'backend 1', to create Volume B on the same backend as A,
use:
cinder create --hint same_host=VolA-UUID SIZE
To create Volume C on different backend than that of A, use:
cinder create --hint different_host=VolA-UUID SIZE
Now, to create Volume D on different backend other than those of A and C,
use:
cinder create --hint different_host=VolA-UUID --hint
different_host=VolC-UUID SIZE
or:
cinder create --hint different_host="[VolA-UUID, VolC-UUID]" SIZE
