Failover to alternative iSCSI portals on login failure
When the main iSCSI portal is unreachable by network failure etc.,
volume attach will fail even if the array has the other portal
addresses alive. To enable nova-compute and brick (with corresponding
patches) to fall-back to alternative portals, this patch makes Cinder
to contains the multiple portal addresses and corresponding IQNs and
LUNs in connection_info returned by initialize_connection API.
The main portal information is also returned in target_portal,
target_iqn, target_lun for backward compatibility. For example:
This patch makes LVM iSCSI backend return multiple portals,
iqns, and luns when iscsi_secondary_ip_addresses is specified in

target_lun will also be included even if 'multipath=True' is specified

Clear migration_status from a destination volume if migration fails
When some error happens during volume migration, cinder-volume
keeps remaining a destination volume because the volume copy may be
in the completing phase and a source volume may be deleted already.
In this case, the migration_status of the destination volume in
data base should be cleared. As a result, the volume can be handled
properly even if volume migration is failed. If the migration is
in the migrating phase, the volume should be deleted and an entry
of database is also destroyed because the source volume is remaining.
Also there is an another problem that a source volume is remaining
as migrating status if create_export raises exception. In this case,
source volume can't be deleted even if it will be unnecessary.

Limit volume copy bandwidth per backend
Currently, by setting volume_copy_bps_limit in cinder.conf,
volume/image copy can be throttled to mitigate slow down of
instances' volume access during the copy. However, this is a global
setting and applied to all the backends.
This change enables admins to configure volume_copy_bps_limit to
different values among backends by specifying it in each backend
section.
In addition, with this change, the bps limit will be divided when
multiple volume copy operations run concurrently on the same backend.
For example, if volume_copy_bps_limit is set to 100MB/s, and 2 copies
are running on a backend, each copy can use up to 50MB/s.
This behavior will be useful for QoS which ensures a certain amount
of bandwidth is kept for instances' volume access.
This introduces Throttle classes to count volume copies in a backend
and setup bandwidth limit.

Remove warnings for long vgs and lvs calls
We put some warning statements in a while back for
lvs and vgs commands that lasted more than 60 seconds
so we could easily query issues in the gate.
Since then we've made a number of changes to improve our
LVM interactions including the use of an LVM conf file with
a filter for only the VG's Cinder uses.
There's one issue remaining however where during the instance
rescue test in Nova where LVM get's stuck trying to open
devices that no longer exist. Part of this I think is due
to some manipulation that Nova/KVM does on the attached volume
when the test is run, but also the rescue process in Nova
uses LVM volumes as well and does some moving around and mounting
of devices.
The result is that LVM calls can take quite a while
(greater than 100 seconds) to complete during the rescue process.
This doesn't result in any failures, just that the rescue process
slows things down dramatically and is a pretty heavy process.
Also, the newer versions of process utils include completion
timing in the logs so we don't really need this any longer eve
to query timings and get info.
This patch removes those log statements, and proposes we
document somewhere that rescue operations on a setup that
includes c-vol service and nova-compute service on the same
node will temporarily impact LVM performance.
