Explicitly close requests obj in SolidFire Driver
Currently we're not explicitly returning requests
connection objects back to the ConnectionPool when
we're done with them. For most cases this isn't a
problem, however if we start adding higher and higher
concurrent actions the internal Connection Pool management
doesn't keep up.
This patch just adds an explicit close of the requests
connection after we're done with it to keep the ConnectionPool
as full as possible and avoid any resource issues that could
occur during heavy concurrent usage.

Remove test_barbican from keymgr tests

Fix SolidFire inaccurate model on migrated vols
The general migration impl in Cinder works
by creating a new volume, transfering the data
from the original volume to the new volume, and
then deleting the original and flipping the ID
of the new volume.
Turns out we missed the fact that this creates a
mismatch between the volume Cinder will later ask
for and what the volumes identity is on the backend
device.
This change adds a check on create_volume at the drivers
level to see if it's part of a migration and is infact
going to get renamed. If so, just use the new name
and avoid all the headaches that come later with updating
provider auth and location.
The model info won't change in this case and is accessible
independent of the ID field in the Cinder base and the
crazy change that's going to take place on that value
in the Cinder DB.

Eventlet green threads not released back to pool
Presently, the wsgi server allows persist connections hence even after

Because of this problem, the green thread is not released back to the pool.
In order to close the client socket connection explicitly after the

Add ability to update migration info on backend

LioAdm: Delete initiator from targets on terminate_connection
In current LioAdm implementation, initiators are remained even if
terminate_connection is called. This keeps volumes exported to hosts
after instances attaching the volumes are live-migrated to another
host, which is not good for security. It also causes an error on the
migration back to the original host, because cinder-rtstool doesn't
update CHAP authentication if the initiator already exists.
With this patch, initiators are deleted on terminate_conection.
'initiator-delete' operation is added to cinder-rtstool.
It makes the following live-migration succeed.
Also, this adds unit tests for initialize_connection and
terminate_connection methods in LioAdm.
This patch allows an OpenStack environment to run as a secure NAS
environment from the client and server perspective, including having
root squash enabled and not running file operations as the 'root'
user. This also sets Cinder file permissions as 660: removing
other/world file access.
The "nas_secure_file_permissions" option controls the setting of file
permissions when Cinder volumes are created. The option defaults to
"auto" to gracefully handle upgrade scenarios. When set to "auto",
a check is done during Cinder startup to determine if there are
existing Cinder volumes: no volumes will set the option to 'true',
and use secure file permissions. The detection of existing volumes will
set the option to 'false', and use the current insecure method of
handling file permissions.
The "nas_secure_file_operations" option controls whether file
operations are run as the 'root' user or the current OpenStack
'process' user. The option defaults to "auto" to gracefully handle
upgrade scenarios. When set to "auto", a check is done during Cinder
startup to determine if there are existing Cinder volumes: no volumes
will set the option to 'true', be secure and do NOT run as the 'root'
user. The detection of existing volumes will set the option to 'false',
and use the current method of running operations as the 'root' user.
For new installations, a 'marker file' is written so that subsequent
restarts of Cinder will know what the original determination had been.
This patch enables this functionality only for the NFS driver.
Other similar drivers can use this code to enable the same
functionality with the same config options.

Log a warning when getting lvs and vgs takes longer than 60 seconds

This patch adds a check for when getting logical volumes and volume
groups takes longer than 60 seconds and logs a warning if that happens.
This is helpful in production also because the default interval for

warnings from the FixedIntervalLoopingCall in oslo which is controlling
