Cleanup 3PAR/LeftHand failover_host exceptions
The 3PAR and LeftHand drivers were raising the wrong exception,
VolumeBackendAPIException, instead of InvalidReplicationTarget,

Fix up failover_host exceptions to preserve states
UnableToFailOver and InvalidReplicationTarget do not save the state
of replication_status currently. This patch adds host.save() in
order to write the change to the db.
In addition, the manager should honor the current replication state
of the host when InvalidReplicationTarget is raised instead of forcing
it into 'enabled' state.

Move replication_status update to init_with_rpc
We were using host_init to read replication_status from the
driver and update the service entry in the DB. It turns out
that on a fresh install this doesn't actually work, because
while we have multiple init methods for the backend, the
Service entry isn't actually created in a fresh deploy until
AFTER init_host. The result was that in some cases we were
trying to update a column on a non-existent Service in the
DataBase.
This patch moves the replication_status updates for the
service into the init_with_rpc method. That method was
just a noop stub in the parent manager class, so we just
implement it in cinder.volume.manager and do what we need
with the replication update info.
In order to allow a cloud operator to use the policy based
user access control for these operations, a context during
these operations should be elevated before db operations.
After applying this change, the cloud operator can manage
policy for volume type operations like this.
1. To permit volume type operations for specific user,
add "storage_type_admin" role.
2. Add "admin_or_storage_type_admin" rule to policy.json.
"admin_or_storage_type_admin":
"is_admin:True or role:storage_type_admin",
3. Modify rule for types_manage.
"volume_extension:types_manage":
"rule:admin_or_storage_type_admin",

Add volume_type to volume object expected_attrs
We haven't had volume_type in expected_attrs for volume objects lists.
This resulted in situation in which although we were joining the
volume_type explicitely in DB API, the object just dropped the data.
Volume type was then lazy loaded when needed, so every "cinder list"
call was making additional DB queries per returned volume, causing
massive performance drop.
Actually there were two unnecessary DB calls per volume, because not
only volume_type was fetched, but also volume_type.extra_specs as a result
of passing 'extra_specs' in expected_attrs when calling
VolumeType._from_db_volume in Volume._from_db_volume (wow, that's
complicated…).
This commit sorts this out by adding volume_type to expected_attrs to
match what we join in the DB. Please note that I'm not adding
consistencygroup and volume_attachment on purpose - addition causes some
unit tests failure and that late in the release it seems risky to try
fixing that. The changes also required minor rework of expected_attrs
infrastructure in the o.vo layer to be able to pass different values
when we query for just a single volume and when we fetch whole list (as
we're doing different joins in the DB layer in both cases).

Switch failover-host from rpc call to cast
There is some concern that with large numbers of volumes it will be
difficult for drivers to failover the host before the rpc timeout hits.
To avoid asking admins to bump the timeout just for these cases we can
switch it to do a non-blocking cast instead of call. The difference now
being that the active_backend_id is not returned from the API call to
failover-host. An admin will have to look at the service-list output
to see when it has changed states from ‘failing-over’ and then check
what its active_backend_id is at that time.

NetApp: volume resize using clone fails with QoS
Data ONTAP cannot resize a LUN past the geometry established
when the LUN was created. So to resize past that limit, the
DOT drivers create a new LUN of the needed size and clone
the original LUN into it. This process doesn't always work
