Dell Storage Center: Add retries to API calls
In heavily loaded networks we have seen some cases
of temporary ConnectionErrors when making REST API
calls. There are usually successful calls just prior
and immediately after these failures, so it appears
to be a transient condition.
This patch utilizes the recently merged retry decorator
to add some retry handling to the REST API calls when
this condition is encountered.
With a test script looping through repeatedly running
CI against this first patch I was able to validate
that it addresses the issue. Out of 20 runs, a full
2/3 of the tests passed showing that the retry was
used. These test runs would have failed without the
retry.
The output from these test runs can be viewed here:

results.

Refactoring for export functions in Target object
Currently, export functions such as create_export() are implemented
in individual Target code, but most of them are same and these are
common features in each target.
This patch moves these methods to parent ISCSITarget class to
commonalize and each Target simply inherit these methods from parent
class. As a result of this change, LioAdm can inherit ISCSITarget
class directly instead of inheriting TgtAdm class.
This simplifies dependency of targets and improves maintainability.
By refactoring these methods, this patch also fixes following issues.
(a) Fix bug #1410566
After transitioning to the new driver and target model, iscsi_targets
is not added to the table during create_export() phase.
However, remove_export() in LIO Target is still reffering empty
iscsi_targets table. This causes NotFound exception and remove_export()
skips to do remove_iscsi_target().
As a result, iscsi target is not removed and the target continues to
grab the volume(logical volume) as an in-use status.
This patch fix the problem.
(b) Re-export a volume with CHAP
Current Tgt Target recreate iscsi target without CHAP during
ensure_export() even if the volume is exported with CHAP previously.
This patch changes this bahaviour to recreate iscsi target using
previous CHAP which is stored in volume file on state_path dir.

Enhance iSCSI multipath support
Currently, nova-compute and brick support multipath for iSCSI volume
data path. It depends on response to targets discovery of the main
iSCSI portal, expecting multiple portal addresses to be contained.
However, some arrays only respond to discovery with a single portal
address, even if secondary portals are available. In this case,
the connector cannot know secondary portals and corresponding
iSCSI target IQN, so cannot establish multiple sessions for
the target(s). To enable the connector to login to secondary portals,
cinder should tell all the portal addresses and corresponding
target iqns/luns.
With this patch initialize_connection API will return connection_info
with multiple portal addresses/iqns/luns when multipath=True is
specified in the connector info. For example:

Support over subscription in thin provisioning
This patch adds support for over subscription in thin provisioning.
The following changes are proposed:
* A configuration option "max_over_subscription_ratio" will be

* Driver reports the following capacities and ratios:
* provisioned_capacity
* max_over_subscription_ratio
* Driver can use the newly added configuration option to report
this ratio or it can decide what ratio to report itself.
The value of this ratio is depending on driver implementation
and will be reported together with other capabilities and
capacities by the driver.
* reserved_percentage
* Note: This is an existing parameter reported by the driver.
* Currently it is measured against the free capacity. In this
patch, it will be changed to measure against the total
capacity in the filter scheduler.
* Driver also reports the following capabilities:
* thin_provisioning_support (True or False)
* thick_provisioning_support (True or False)
