LVM: Pass volume size in MiB to copy_volume() during volume migration
Currently migrate_volume() in lvm.py does not pass volume size in
MiB but passes volume size in GiB to copy_volume(). The size argument
of copy_volume() requires MiB value. As a result, if the volume size
is 1GiB, copy_volume() copies only 1MiB head of 1GiB volume to the
destination volume, and then the volume data is corrupted.
This patch fixes to pass volume size in MiB.

Dell: Added support for update_migrated_volume
Added support for updated_migrated_volume to common driver.
Added rename_volume to dell_storagecenter_api to support it.
Added tests to test_dellsc.py and test_dellapi.py.
The only thing we do in this rename the newly migrated volume
destination volume on the Dell Storage center to be the same
as the original volume ID. Since we identify the volumes
by volume ID this prevents them from being lost.
When attach is called twice for the same volume and instance the
attach_volume checks if the attachment already exists and returns.
This leaves the volume in 'Attaching' state. The volume status should
be reset to 'in-use' if we see the attachment already exists.

Add external genconfig calls
After moving to oslo.config we still were using
incubator config generator. This was ok, but the
problem is we haven't been pulling config options
from the oslo libs.
This is a hack that just appends external lib calls
and appends those options to the sample file being built.
service.py had some code where the child process would catch the
SIGTERM from the parent just so it could exit with 1 status rather
than with an indication that it exited due to SIGTERM. When
shutting down the parent doesn't care in what way the child ended,
only that they're all gone, so this code is unnecessary.
Also, for some reason this caused the child to never exit while
there was an open connection from a client. Probably something
with eventlet and signal handling.

Windows SMBFS: fix volume extend
The Windows SMBFS driver inherits the Linux SMBFS driver,
overriding Windows specific methods.
This commit Ic89cffc93940b7b119cfcde3362f304c9f2875df added the
volume name as an extra argument to the _do_extend_volume in order
to check if differencing images are pointing to backing files other
than the according volume disks.
Although this is not required on Windows, this method should accept
this extra argument in order to have the same signature as the
method it overrides. At the moment, this raises the following

Include boot properties from glance v2 images
In order for users to take advantage of COW volumes created from
a glance image, Cinder must be configured to use Glance API version
2 (default is 1). In version 2, the required boot metadata (kernel_id
and ramdisk_id) are no long stored in the 'properties' dict, but as
standalone fields in the GET response from glance. The existing cinder
parser for the glance request is not aware of this and the volume
created form a v2 image will lack this required metadata.
This was causing the recent Ceph CI gate failures for
test_volume_boot_pattern.

Delete the temporary volume if migration fails
Issues resolved in this patch include the following changes:
* A temporary volume is created on the destination host before migrating
the data from the source. However, if the creation of this volume fails,
its record will be left in the database as redundant information. This
patch will remove the database record if the creation fails.
* If attaching the remote dest volme fails at initialize_connection
due to timeout, we need to terminate the connection. Otherwise, the dest
volume will not be released and successfully deleted.

Dell SC driver has insufficient iscsi logging
In the case where a volume was mapped but the server could not
locate the volume not enough information was being logged to
sort out the failure. Added logging to Dell SC ISCSI driver.
Now returns much more connection information on trying to map
a volume. Also tries to return iscsi properties associated with
the controller on which the volume in question is active.
Copying preallocated image to volume involves creating
a virtual disk using the image. The virtual disk has a
descriptor and an extent. The preallocated image is used
as the flat extent to create the virtual disk.
To create virtual disk from preallocated image, we first
create a temporary virtual disk (with a descriptor and
flat extent), then replace its flat extent with the
downloaded image. Since vSAN datastores do not support
flat extent, the above operation fails if such a datastore
is selected for virtual disk creation. This patch fixes
the problem by not selecting vSAN datastores for temporary
virtual disk creation.
