Port to oslo.messaging
The oslo.messaging library takes the existing RPC code from oslo and
wraps it in a sane API with well defined semantics around which we can
make a commitment to retain compatibility in future.
The patch is large, but the changes can be summarized as:
* oslo.messaging>=1.3.0a4 is required; a proper 1.3.0 release will be
pushed before the icehouse release candidates.
* The new rpc module has init() and cleanup() methods which manage the
global oslo.messaging transport state. The TRANSPORT and NOTIFIER
globals are conceptually similar to the current RPCIMPL global,
except we're free to create and use alternate Transport objects
in e.g. the cells code.
* The rpc.get_{client,server,notifier}() methods are just helpers
which wrap the global messaging state, specifiy serializers and
specify the use of the eventlet executor.
* In oslo.messaging, a request context is expected to be a dict so
we add a RequestContextSerializer which can serialize to and from
dicts using RequestContext.{to,from}_dict()
* The allowed_rpc_exception_modules configuration option is replaced
by an allowed_remote_exmods get_transport() parameter. This is not
something that users ever need to configure, but it is something
each project using oslo.messaging needs to be able to customize.
* We maintain a global NOTIFIER object and create specializations of
it with specific publisher IDs in order to avoid notification driver
loading overhead.
* rpc.py contains transport aliases for backwards compatibility
purposes. setup.cfg also contains notification driver aliases for
backwards compat.
* The messaging options are moved about in cinder.conf.sample because
the options are advertised via a oslo.config.opts entry point and
picked up by the generator.
* We use messaging.ConfFixture in tests to override oslo.messaging
config options, rather than making assumptions about the options
registered by the library.

get volumes API does not handle limit=0
This bug fixes a regression from bug 1288429, where the "next"

maximum limit (even if the "limit" param is not specified).
The regression is hit when a "limit" of 0 is specified; in this
case the logic to create the "next" link is still executed and an
exception is thrown. The fix is to add back in the "if" check that
implictly checks if the max_items is non-0.
Test code was also created to verify that a limit of 0 is handled

NetApp implementation for copy offload in clustered nfs driver
The Copy offload binary is a special RPC implemented in Ontap that
allows NFS clients to ask the server to copy data between
volumes in the same cluster efficiently. The special
binary will be developed by NetApp and distributed to its customers.
It will address two copy cases after efficient image clone failed.
First when image cache file is present in a different share than
the one holding volume. Second when glance is backed by nfs share
which is on the same cluster as nfs driver backend. Instead
of regular http download the copy offload workflow will be used to copy
image to share and volume. Resubmitting it as there was a problem

Remove str() from LOG.* and exceptions
This commit removes the use of str() from LOG.* messages
and exceptions.
The reason we need to remove str() is because str() will fail if
it gets a Unicode string that has something that doesn't translate
to ASCII in it. If such a situation is encountered you will lose
the message string in question. In most cases, the use of str() is
unnecessary for LOG.* and exception messages. Using %s is smart
enough to figure out what to do with what it is passed. It first
tries to str() it, if this fails it falls back to using unicode. Either
way, the result will then be something that gettextutils can
handle and translate.

Volume manage/unmanage support
Implements: blueprint add-export-import-volumes
Volume manage/unmanage support.
This change adds two new API extensions:
volume_unmanage.py:
Adds an "os-unmanage" action on an existing volume, which causes a
delete operation to flow through the stack, with a flag that indicates
that a different method ("unmanage") should be called on the driver
instead of delete_volume. A default, empty, implementation of unmanage
is provided.
volume_manage.py
Adds a new "os-manage-volume" API. A POST to this URI is very similar to
volume creation, except that the images, snapshots and existing volumes
cannot be specified. Instead the following must be specified:
host: Cinder host on which the existing storage resides
ref: Driver-specific reference to the existing storage object
name, description, volume_type, metadata and availability_zone are
supported as per a normal volume creation.
In order to support some re-use between volume_manage and the regular
volume creation, add_visible_admin_metadata has been factored out into
the cinder utils.py module.
The rest of the changes are just the implications of the host/ref
specification moving through the api, rpcapi, manager and flow (API and
Manager) layers. Management of an existing volume causes the
manage_existing_get_size() and manage_existing() methods to be called on
the driver, and a reference LVM implementation is provided.
brick/local_dev/lvm.py now includes a method to rename an LV.

Fix HP LeftHand migration with snapshots
Check for snapshots associated with volumes during assisted
migration, and fail if a snapshot is found.
When a volume is cloned on the HP LeftHand array, a snapshot
is created and the cloned volume is created from the snapshot.
The snapshot remains associated with the newly created volume.
Therefore, backend assisted migration should check for volumes
with snapshots and not use native APIs to migrate any volume
that has a snapshot.
Currently the PBM wsdl files have to be downloaded to the local file
system and needs to be configured in 'pbm_wsdl_location'. If it is
manually configured then PBM feature is enabled.
This patch does away with the manual configuration of
'pbm_wsdl_location'. PBM wsdl files are now shipped with the driver.
VC version is fetched from the backend server and the corresponding
wsdl file is used. If the backend is a VC version that is less than
5.5 then PBM feature is turned off.
Adding support for a global pbm policy configuration for the vmdk
driver. Setting the 'pbm_default_policy' in cinder.conf will be
used as the default storage profile name to be used when creating
a volume without associated vmware:storage_profile extra spec.
Also renaming 'vmware-pbm-wsdl' to 'pbm-wsdl-location' to use
nova driver's naming convention.
vmware: check datastore availability during create
The vmdk driver does a lazy creation of the volume's backing vmdk
only at attach time. This is done to save on the huge copy cost
if the vmdk needs to be moved 'closer' to the VM instance at
attach time.
Still during a create volume call the driver needs to verify
availability of a suitable datastore that matches the given
storage profile as well as capacity to accommodate the given
volume size. This check needs to happen at three places - create
volume, create volume from snapshot and create volume from another
source volume.
This change adds a new feature to vmdk cinder driver. Users will be
able to specify a vSphere storage policy in a volume-type. Creating
a volume with this volume-type associates the volume with the
storage policy in vSphere. The driver places this volume only on a
datastore that satisfies this storage policy.
