Add new persona value in the 3PAR driver
A new persona type, '12 - OpenVMS' was added to the list of valid
personas in the 3PAR drivers. This persona was introduced in the

Call get_session() only when necessary
A Session instance should be retrieved only when it's
really needed, e. g. to make a few DB queries inside a
single transaction or to pass the session to a private
DB API method, etc. At the same time, many queries are
simple and can be expressed by the means of auxiliary
model_query() function.

Fix volume_create()/snapshot_create() DB methods
volume_create() and snapshot_create() DB API methods create
entities and return information about them by calling
_volume_get() and snapshot_get() methods. There is no need
to create a new transaction to call the corresponding 'getter'.
Unfortunately, fixing this breaks two existing tests, which rely
on the current behaviour of these DB API methods: both volume_create()
and snapshot_create() raise exceptions, nevertheless new entities are
created.

Execute DB API methods in a single transaction
Many DB API methods do a few queries to a DB (e. g. SELECT
and then UPDATE, or SELECT and then DELETE, etc). By default,
a Session instance is used with autocommit=True, which means,
that each query to a DB is done in a separate transaction. This
is error-prone (as it may lead to race conditions or returning
of unexpected results) and makes rollbacks harder (if one of
transactions fail, the previous ones can not be rolled back).
This patch ensures that all DB API methods, which do a few
queries (or call private DB API methods), are executed inside
a single transaction.
Pop out 'offset' and 'limit' before use for filter
In previous code of _items() from api/v{1,2}/snapshots.py,
and also the _items)_ from api/v1/volume.py.we didn't pop
out the 'offset' and 'limit' fields from HTTP get params
before we use such params for filter.This is the root cause
for bug #1205956
For non-admin user, since 'offset' and 'limit' is not in the
allowed_search_options, so the volumes.remove_invalid_options
will help to filter them out. As a result, it walks around this
bug.
But for admin user,the volumes.remove_invalid_options will not
try to filter the search_options.So for admin user, the 'limit'
will appear in search_options, then obviously get no result.

Create volume from snapshot must be in the same AZ as snapshot
This issue and patch also apply to cloning volumes.
When creating a volume from a snapshot we need to pick the
availability zone of the snapshot's source volume. This patch
goes further and enforces that the new volume must be in the same
AZ as the snapshot. It raises an user error if the user tries
to create a volume in a different AZ to the snapshot.
This is enforced across all drivers because creating a volume from
a snapshot is implemented in the drivers and not all drivers are
guaranteed to support creating a volume from snapshot is a foreign
AZ. More to point if you don't support create a volume like this,
and we allow this then you can create volumes and instances that
get stuck in some weird states that require a support call to fix.
If you do support cross AZ functionality then you can override
the enforcement of that cloned volumes most be in the same AZ
as their source via the 'cloned_volume_same_az' option.

Migration for detached volumes with no snaps.
Implementation of volume migration for detached volumes with no
snapshots. Migration is initiated by an admin API. The scheduler
confirms that the specified destination host can accept the volume.
The source driver is given the opportunity to migrate the volume on
their own. Otherwise, a new volume is created on the destination, both
volumes are attached, the data is copied over, the volumes are
detached, the source is deleted, and the destination is renamed. In
the database, the destination volume's attributes are copied to the
source so that the volume-id remains unchanged, and the destination
volume row is deleted.

Add create & attach times to SolidFire attributes.
This change simply adds create_time and attach_time to
the SolidFire devices attributes.
Times are taken from the volume-ref object, attach_time
is only set/present after an attach, and is also removed
from the attributes list on a detach.
This also required that we actually set attach_time on the
volume in the db. We have the column, but we weren't actually
setting it, so this change required that be fixed.
In the future we should also look at changing the attach_time
from a string to a proper date-time object.

3PAR Driver modifications to support QOS
Currently, the OpenStack HP 3PAR Fibre Channel (FC) and iSCSI Drivers
do not support Quality of Service (QoS) extra specs. The QoS settings
added in this patch include;
• maximum MB/second (maxBWS)
• maximum IO/second (maxIOPS)
These new extra specs will be scoped keys, the scoping will be
qos:maxBWS and qos:maxIOPS. A new key hp3par:vvs was also
added to allow the admin to predefine QOS settings on a 3PAR
virtual volume set and any volume created would be added
to that predefined volume set.
The 3PAR storage arrays set these values on virtual volume sets,
not the actual volume. So the change includes creating a virtual
volume set with these settings and then adding the volume to the
volume set.
1. Max IO/S & Max MB/S are not QoS guarantees
2. These are per volume maximums which the 3PAR is guaranteed
not to exceed.
3. Settings these values does not guarantee these performance
rates will be achievable
Moved to using brick to get connector info and fixed a small bug to get
tests working on real storage again. Also fixed up simulator to handle
the multihostmap case properly.
