Add test case for volume_encryption_metadata_get
This change adds unit tests for the volume_encryption_metadata_get
function. The unit tests provide protection against regressions when
refactoring this code as part of follow-up patches.
Writing the unit tests also exposed a minor issue with the existing
implementation of the volume_encryption_metadata_get function. If the
volume type is not encrypted, then the existing implementation would
raise an exception due to volume_type_encryption_get returning None.
In practice, this issue would not be encountered due to separate
checks to ensure that the volume type is encrypted, but a small
refactoring obviates the need for these checks and allows the
volume_encryption_metadata_get function to be invoked for both
encrypted and "normal" volumes.
A separate patch will clean up the unnecessary checks to ensure that
the volume type was encrypted prior to calling this function.

NetApp E-Series: Fix instance live-migration with attached volumes
Currently, live migrations of instances with attached volumes that live
on a NetApp E-Series backend will fail and break connectivity to the
guest. This patch adds the 'netapp_enable_multiattach' configuration
option that enables multiattach operations with the E-Series driver.
It defaults to allowing these operations but needs to be configurable
since allowing for multiple attachments imposes a limit of 256 volumes
on the backend due to how multiple attachments must be managed by
E-Series.
Multiattach operations are enabled by mapping volumes to an E-Series
host group on the backend called 'cinder-host-group'. Host groups can
only have 256 mappings at a time and so we must limit the number of
volumes in order to guarantee any volume created could then be attached.

Remove force check from copy_volume_to_image
The upload_volume_to_image method allows a force parameter that will
upload a volume even though the volume is attached/in-use. A user can
get away with this with the LVM driver because the LVM backing is
local to the Cinder worker node that's pushing the bits to Glance.
The problem is, this only works for local storage, it won't work
with any iSCSI devices because they can't do multi-attach. Also,
the reason we required that a volume NOT be in-use for this
operation is because we have no way of keeping the guest Instance
from writing to the volume while we're uploading, and corrupting the data.
This has been exposed like this for several releases, so removing it
now likely would not be a good user experience. Instead, this
patch add a config option to enable/disable it (default is to
disable), and deployers can choose whether they would like to
allow the use of --force True or not.
DocImpact Disables the --force option to copy-volume-to-image and
introduces "allow_force_upload" boolean option to re-enable
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.

VolMgr: reschedule only when filter_properties has retry
In the task flow for volume manager, create_volume tasks, volume gets
reschedule even when scheduler doesn't indicate so. The problem is
the flow should not only check 'allow_reschedule' and 'request_specs',
but also (more importantly) filter_properties['retry'], which is
populated by scheduler if schedule_max_attempts is set to > 1. This
checks was there before taskflow was introduced, but somehow the
migration missed the check for filter_properties['retry'].
This change adds back the check, so scheduler_max_attempts won't be
treated like scheduler_max_attempts = infinite.
This patch adds the fix that exists in the nova
libvirt volume code to use oslo_utils strutils
to mask passwords that might show up in debug log
messages.
Current RBD driver assumes ceph cluster name to be 'ceph', for
cluster has a different name, the driver won't be able to connect
to the cluster. This change add a new config option
'rbd_cluster_name' to address this issue.
This allows operations that do not conflict with each
other (i.e. are on different volumes) to run concurrently.
The prior locking scheme was too coarse and essentially
made the driver single-threaded.
This patch moves the implementation of the GlusterFS driver locking
scheme to the RemoteFS base driver so that other similar volume
drivers can use it.

Fix LUN misalignment issue with NetApp iSCSI drivers

So when a pool is in the 3 states, its free capacity is de facto 0.

Logging not using oslo.i18n guidelines (brick)
Multi-patch set for easier chunks. This one addresses

Updates have already been made to the os-brick project.
There have been quite a few instances found where the
i18n guidelines are not being followed. I believe this

correctly do this. Other developers see this code and
assume it is an example of the correct usage.
This patch attempts to clean up most of those violations
in the existing codebase to hopefully help avoid some of
that confusion in reviews.
Some issues address:
* Correct log translation markers for different log levels
* Passing format values as arguments to call, not preformatting
* Not forcing translation via six.text_type and others
Guidelines can be found here:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html
Hacking checks will not be able to identify all violations of
the guidelines, but it could be useful for catching obvious ones
such as LOG.info("No markers!").
