Fix LIO target helper when missing targetcli
After patch to fix LIO target persistence was merged, a bug was
introduced where target creation/removal would result in an exception if
targetcli is not installed on the system.
This patch fixes this by checking if path to the default file exists on
the system and creating it if doesn't.

Introduce Guru Meditation Reports into Cinder
This commit integrates functionality from the
`openstack.common.report` module into Cinder.
This enables Cinder services to receive SIGUSR1
and print a Guru Meditation Report to stderr.
The required modules were added to
'openstack-common.conf' as well.
It is essentially a copy from implementation of
nova side.

Wait until service thread is done on service stop
In order to be able to perform graceful shutdown of services, we need
to wait for all the current service threads to finish before exiting
from the service process.
Oslo.service provides this facility through it's wait() method, so we
need to call it in Cinder Service stop() method which gets called when
graceful shutdown is requested by sending the process SIGINT or SIGTERM.
This patch enables the reporting of the
multiattach capability in get_volume_stats.
The scheduler currently filters on the capability

Replace dict.iteritems() with dict.items()

The iteritems() method of Python 2 dictionaries was renamed to items()

must be replaced with items(), six.iteritems() should not be used. In
OpenStack, the overhead of creating a temporary list with dict.items()
on Python 2 is negligible.
Enables native support for HGST Solutions software Spaces as
Cinder volumes or snapshots.
Each Cinder Volume or Snapshot is mapped to a single HGST Space.
This space may be named differently from the actual volume/snap ID
and so we store the Space Name<->ID mapping in the volume provider_id.
Snapshots are not supported with the current HGST Solutions
software, so they are implemented as heavyweight copies in the
driver.
All Spaces are made visible on the Cinder host for speed of access,
and only the spaces requested by Nova instances are actually made
visible on other members of the cluster.
Not all nodes need SSD storage to take advantage of these volumes,
cinder.conf entries specify which nodes share their local SSDs.
Prerequisites:
HGST Solutions is a software-SAN-like package which allows local
SSDs in a cluster to be combined into a single storage pool.
The driver has a series of configuration options which must be set
in the cinder.conf, prefixed with hgst_*.
Nodes should have the HGST software installed and connected to the
HGST domain prior to rolling out Nova nodes using this storage.
Additional patches required for full functionality (being tracked
under the same blueprint):

Add secondary account capability to SolidFire
The SolidFire Cluster has a limit of 2K volumes per SolidFire
account. Given that the SolidFire account maps directly to the
OpenStack tenant this can be a limitation for some large scale
deployments that may have tenants that wish to create more than
2K volumes in their OpenStack cloud.
This patch introduces the concept of a secondary account for
an OpenStack tenant on the SolidFire backend.
If an OpenStack tenant has more than 2K volumes, and wishes to
create additional volumes, we can create a secondary/supplemental
SolidFire account that is owned by the same OpenStack tenant.
If they wish to go beyond 4K volumes... well, SolidFire V3
driver will deal with that, for now 4K is a line in the sand.
While working on unit tests, we again move to using mock
opportunistically. In addition, a few tests that either
weren't actually testing anything, or were just a fake-loop
that didn't actually work have been removed:
NOTE:
This patch is a temporary for backporting purposes, we are
still planning a refresh in Liberty of the driver.
