Add Fujitsu ETERNUS DX Volume Driver (FC part)
As I explained in my blueprint,
this patch completes Fujitsu ETERNUS DX Volume Driver.
Fujitsu ETERNUS DX Volume Driver consists of two parts, iSCSI and FC.
The iSCSI part [1] had been reviewed and
thanks to the nice reviews, it's merged.
The iSCSI and FC parts have a lot of common codes,
and all the common codes are included in the iSCSI part.

Following the upgrade to hacking version 0.10.0 the H105 issues were

Add BackupStatus enum field
This change adds a new enum and field, BackupStatus and
BackupStatusField, that will hold the constants for the 'status' field
of the Backup object. This enum and field are based off the base
oslo.versionedobjects enum and field. This also changes over the Backup
object to use the new field (and bumps the version so newer versions
know to enforce valid values). Finally, all uses of strings for
comparison and assignment to this field are changed over to use the
constants defined within the enum.

Fix race conditions in migration 061
Migration 061 is supposed to add new `data_timestamp` field and populate
it with value of `created_at` column. This was done by selecting all the
backups and doing updates one-by-one. As it wasn't done in transaction
solution was prone to race condition when a new backup is added while
running the migration. This means that this migration could cause
problems when running in live environment. With blueprint
online-schema-upgrades we want to make Cinder able to perform migrations
live.
A solution is to change this statement to a single DB query which
updates all the rows. This commit also removes unnecessary update to
snapshot_id added there. As this column is nullable it will by default
be NULL, so there's no need to set it manually to that value.
As before and after this commit the migration does logically the same,
this should be safe even if someone is doing inter-release deployments.
An alternative would be to simply add transaction to the update step in
the migration, but that would effectively lock the table for longer
period of time than atomic one-query update.

Updated "deleted" column of volume_type_access

value of "id" in "deleted" column during volume type access remove

Enhance the stats reported from the Pure Volume Drivers
This change provides some improvements for older scheduler hints and
stats along with a few new stats that can be used for filtering and
goodness functions. These new stats include:
Latency:
usec_per_read_op - Average arrival-to-completion time, measured in
microseconds, for a host read operation.
usec_per_write_op - Average arrival-to-completion time, measured in
microseconds, for a host write operation.
queue_depth - Average number of queued I/O requests.
IOPS:
reads_per_sec - Number of read requests processed per second.
writes_per_sec - Number of write requests processed per second.
Bandwidth
input_per_sec - Number of bytes read per second.
output_per_sec - Number of bytes written per second.
Metadata:
total_hosts - Total number of Purity hosts created.
total_snapshots - Total number of snapshots (includes pending
deletion).
total_pgroups - Total number of Protection Groups (includes
pending deletion).
Note: All of these stats are for the entire array and are not specific
to the Cinder volumes, snapshots, hosts, latency, etc.
As part of the new and improved stats the drivers will respect the
cinder.conf backend “reserved_percentage” option. Previously it was set
to 0.
Last but not least there is a new config option called
“pure_automatic_max_oversubscription_ratio”. This defaults to True, and
when enabled gives the older behavior of automatically calculating the
thin provisioning ratio which was allowed for the backend. If disabled
the driver will now respect the “max_over_subscription_ratio” config
option.
