This patch just pulls the actual account object out of the response

Adds the random option to cinder retry function
The current retry functionality in Cinder, always uses fixed
numbers to define the time to wait before performing the next
attempts. This behaviour can make the retries of multiple
requisitions to collide in each attempt as they will wait the
same amount of time and try to use the same resource together
again.
This patch changes the behaviour of cinder.utils.retry() to
receive a parameter that allows the function to implement
randomly generated wait intervals.

Test whether sample config generation works
Adds --checkonly to tools/config/check_uptodate.sh.
This allows verifying that a configuration file was
generated.
We have had a number of issues introduced which
have caused config file generation to fail since we
removed the sample config file check in the gate.
This does not add back checks to ensure that the file
has been updated, it only checks to ensure that it is
still possible to update the sample file.
Adding optional dependency tracking would be nice,
but Cinder is not yet in a place to do this.
- Cinder supports tox 1.6 (minversion in tox.ini)
- This functionality does not work on 1.6, requires 1.7. Tox
fails to build a test environment if using tox 1.6.
- We have decided we can't move to tox 1.7 for now.

Register the volume_opts config options in remotefs.py
With commit bc23e0bf415defb1956c9864ac33390bb4cc2017 a new
volume_opts configuration option list was added into
cinder/volume/drivers/remotefs.py. This new list, however,

genconfig cannot figure out the right place to put the config

once again, able to generate the sample file.

Dell SC: Fix error causing missed log message
Extremely trivial fix. An extra comma at the end of a
logging line actually made it into a statement that
doesn't perform logging. This patch removes the extra
comma so that the message gets logged as expected.
Capacity filter uses free_virtual capacity to filter out a host if
thin provisioning is enabled and over-subscription ratio is less
than or equal to max_oversubscription_ratio. The current formula
for free_virtual is not calculating the real free virtual capacity.
Rather it computes "adjusted" free virtual capacity which is the
current free capacity (after taking into account of reserved space)
we can over-subscribe. This patch adds necessary documentation and
renames free_virtual to adjusted_free_virtual to clarify this.

Add volume migration support for Huawei driver
If the target host and the original volume are on the same array,
then Huawei driver will do the migration now instead of having
it done by the general migration process.
In vCenter inventory, volumes are organized under the folder:
<datacenter_vm_folder>/<volume_folder>, where <volume_folder>
is the value of driver config option 'vmware_volume_folder'.
Due to this organization certain project-specific maintenance
tasks (using vSphere client) might be difficult for vCenter
admin. For example, the admin may need to migrate the volumes
of a particular project from one vCenter datastore to another.
This patch changes the folder hierarchy to:
<datacenter_vm_folder>/OpenStack/Project
(<project_id>)/<volume_folder>
for better organization.

Modified default value of config option
'vmware_volume_folder' and updated its description.

3PAR: Adding performance metrics to volume status
If one storage backend has high load while another has lower load,
when a user/admin creates a volume, the current evaluator/scheduler
may place the volume on the backend with higher load. In many cases,
the evaluator/scheduler should place that volume on the backend
with the lowest load for load balancing purposes. In general, for load
balancing virtual volume placement, an evaluator/scheduler needs
access to performance metrics (e.g. IOPS throughput, bandwidth,
latency, IO size) to measure load, but Cinder drivers don't generally
report those metrics.
Although these performance metrics are available from the 3PAR CLI,
they are currently inaccesible in the evaluator/scheduler. The
proposed changes add these metrics to the volume status report and
thus make them accesible by the evaluator/scheduler.
In cinder/volume/drivers/san/hp/hp_3par_common.py, uses the 3PAR
client method HP3parClient.getCPGStatData to get performance metrics,
and adds new fields in the output of HP3PARCommon.get_volume_stats
corresponding to the performance metrics: IOPS throughput, bandwidth,
latency, io_size, queue_length, and avg_busy_perc. These metrics are
taken by averaging samples taken once per day for the last week.
In cinder/tests/unit/test_hp3par.py, adds unit tests in
TestHP3PARFCDriver.test_get_volume_stats and in
TestHP3PARISCSIDriver.test_get_volume_stats.
