Storwize SVC multiple management IPs
Right now Storwize SVC does not support multiple management IPs.
This patch adds this feature so that if the primary IP fails, it
will switch to the secondary IP that the user sets.
We had the call in the manager as part of a periodic,
it did nothing at all. Some drivers had comments "no idea
what to do with this", even better we had unit tests that
faked out a call that returned nothing and asserted it was
nothing. ?!?

[LVM] Restore target config during ensure_export
If server crash or reboot happened, LIO target configuration
will be initialized after boot up a server. Currently, Cinder
has a functionality to save LIO target configuration to save
file at several checkpoint.
If LIO target service is configured properly, LIO target
configuration is restored by this service during boot up
a server, but if not, existing in-use volumes would become
inconsistent status after c-vol service starts.
If there is no iSCSI target configuration during
ensure_export, LIO dirver should restore the saved
configuration file to avoid the problem.

Add SIGHUP handlers to reset RPC version pins
Adding SIGHUP handlers (by implementing reset from oslo.service) to
cinder-scheduler, cinder-backup and cinder-volume that reset cached RPC
version pins. This is to avoid the need to restart all the services when
upgrade of the deployment is completed.
Some changes go a little deep into the stack, because to reload all the
pins we need to recreate <service>.rpcapi.<service>API objects that are
stored in the memory.
Please note that SIGHUP signal is handled by oslo.service only when
service runs in daemon mode (without tty attached). To test this commit
in DevStack you need to add "&" to the end of the command that starts
the service.
Situation is more complicated with the API service, so we're leaving it
with restart required for now. In the deployments with HA cinder-api is
typically behind a load balancer, so restarting individual nodes
one-by-one should be easy.

Rtstool sets wrong exception message on save
Rtstool does not properly set the message on the RtstoolError exception
on the save_to_file method (save operation) because it's passing
formatting arguments as if it were a LOG call instead of formatting
those same arguments with
%.
There are 2 cases where this can happen, when saving to the default
location on a system that has no target.service installed and the
creation of the default directory fails, and when saving the file
actually fails.
This patch properly formats the message before passing it to the
instantiation of RtstoolError exception.

Split out NestedQuotas into a separate driver
Fixes the following issues with NestedQuotas:
* Requires conf setting change to use nested quota driver
* Enforces default child quota value with volume creation
* Disables the use of -1 to be set for child quotas
* Adds an admin only API command which can be used to validate
the current setup for nested quotas, and can update existing
allocated quotas in the DB which have been incorrectly set
by previous use of child limits with -1
There will be follow-up patches with the following improvements:
* make -1 limits functional for child projects
* cache the Keystone project heirarchies to improve efficiency
Note: ideally validation of nested quotas would occur in the setup
of the nested quota driver, but doing the validation requires a
view of ALL projects present in Keystone, so unless we require Keystone
change to allow "cinder" service user to be able to list/get projects,
we need the admin-only API for validation that should be called by
cloud-admin.

related to the backups on current host. Backing-up volumes can
be found with field backup.volume_id. Restoring volumes are found
by new field backup.restore_volume_id.
