[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.

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.

Roll back reservations quota in RPC if necessary
Currently the latest version of the volume rpcapi passes along
old_reservations in retype whereas older versions do not. In the
case where old_reservations aren't passed, they will be checked again
in c-vol. This patch rolls back the quotas that were checked for
old_reservations if the client can't send the latest version in
the RPCAPI so that they aren't reserved twice.
This is an amendment to this recently merged patch:

Scaling backup service
Currently the cinder backup service is tightly coupled to the cinder
volume service in ways that prevent scaling out backup services
horizontally across multiple physical nodes.
This patch is to loosen this coupling to enable backup processes
to run on multiple nodes without having to be colocated with volume
services.
The following works are not included in this patch:
1. Remote attach snapshot.
2. Vendor specific work.
3. Remove current backup_volume in driver.
4. Rolling upgrades.

Add restore_volume_id in backup
This patch is to add restore_volume_id in backup object.
When restoring a volume from a backup, it saves the
volume in backup object.
Currently volume service and backup service are in same host.
When backup service starts, it does cleanup tasks on both
backups and volumes on current host.
But with bp scalable-backup-service, backup service and
volume services can run on different hosts. When doing cleanup
tasks, we need to find out backing-up and restoring volumes
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.
