Enable multi-process for API service
Due to the limit of Python interpreter, API service of Cinder can't
really utilize underlying multi-core architecture even libraries
like eventlet has been used. To make API service much more scalable,
we'd adopt multi-process (worker) mode that has been used for long
in Glance/Swift/Nova.
The default behavior isn't changed with this patch, Cinder API
service will still run in one process (default value of
osapi_volume_workers is None).
Implementation wise, a good portion of cinder/service.py has been
removed because those content has been merged in Oslo version of
service module. cinder/wsgi.py is also updated to adopt the change
for multiple WSGI servers running in separate processes.
Implement bp: multi-process-api-service
DocImpact: 'New config option osapi_volume_workers is used to specify
number of API service workers (OS processes) to launch for Cinder
API service. Setting this config option to a proper value (e.g.
osapi_volume_workers = # of CPU cores/threads of the machine) can
greatly improve the total throughput of API service [# of API
requests can be handled per second].'
Also removed out-dated comments in bin/cinder-api due to the fact
that this bug [1] has been fixed in eventlet 0.9.13

Add support for retype in Storwize/SVC driver
In Storwize/SVC, retype can be handled by a few cases:
1. The change may just require setting an option on the volume
2. The change may require moving the data in the same pool (e.g.,
compression)
3. The scheduler may have chosen a different pool virtualized by the
same Storwize or SVC, in which case we move the data as in #2
Brick's TargetAdmin classes have a
default value set in __init__ for
iscsi_target_prefix. The unit test was changing
the value returned for the internal _get_target,
but wasn't changing the CONF.iscsi_target_prefix to
match. So the default value in the __init__ was
being used and hence the differences.
This patch sets the configuration's iscsi_target_prefix
which alters the values passed into the driver. This
also makes the tests consistent between the iqn of the volume
at create time and delete time.
Fix up calculating space info for mirrored volumes
The status reporting in the lvm driver for cinder volume incorrectly
reports free capacity. This is due to a couple of issues:
a) the number of mirrors isn't taken into account

because all mirrors must be on separate physical volumes.

Allow user to specify audit period.
The script 'cinder-volume-usage-audit' is generally run by cron to
generate volume and snapshot exists audit notifications that can be
consumed by ceilometer or other auditing systems. In this mode it sends
notifications for volumes that existed in the 'last completed audit
period' as calculated by cinder.utils.last_completed_audit_period()
However, it may sometimes be necessary to be able to send notifications
for audit periods other than than the last completed audit period. For
example if the host running the audit script was down for a period.
This patch provides three optional command line parameters to the script
cinder-volume-usage-audit. If no parameters are provided then the
operation of the script is unchanged. If parameters are provided then
they have the following effects:
--start_time specifies a date and time that is used in place of the
start of the last completed audit period.
--end_time specifies a date and time that is used in place of the end of
the last completed audit period.
--send_actions As well as sending exits notifications the script will
send any create or delete notifications that would have been sent during
the specified audit period.

Use a mirrored mirror log
By default, LVM will sync the two mirrors of a logical volume on
creation. This is I/O intensive and it takes a long time though, so we
tell it not to with --nosync. The next default behavior is to create a
mirror log which says what portions of the mirrors are in sync. But
then if a disk backing a mirror log fails, we have to deal with
resyncing the mirrors at each reboot.
This commit tells LVM to use a mirrored mirror log, which will use
approximately 4MB of extra space, but means we'll never have to
sync mirrors, ever.

Move driver initialization check into the method
Volumes and backups managers' methods are decorated with
`require_initialized_driver` which checks whether the driver has been
initialized or not. The decorator fails with a `DriverNotInitialized`
exception if the driver hasn't been initialized.
This early failure leaves volumes and backups in a wrong status which is
not just confusing for the user but it also makes it difficult to do
anything with the resources after they've been left in a 'bogus' status.
For example, when a volume creation is requested, the volume is first
created in the database and its status is set to 'creating'. Then the
scheduler will pick an available volume node and send the task to it. If
the driver has not been initialized, the volume status will be left as
'creating' instead of 'error'.
This patch fixes that issue by moving the driver initialization check
into the various manager's methods. In some cases this check is done at
the very beginning of the method, in some others - either to avoid code
duplication or because the lines above the check made sense to be
executed first - this check is done later in the method.
