Implement QoS support for volumes
This patch is to implement generic Quality-of-Service(QoS) support for volumes.
The goal is to add an interface so that cloud/Cinder admins can use to set
volume QoS, which can be enforced either in hypervisor or on Cinder back-end
or both. QoS specifications are added as a standalone (only visible to admin)
entity. So admin can create/update/delete and associate/disassociate QoS
specifications to other entities, in this case volume types.
Note that while it's possible for Cinder to set the granularity of QoS control
to every single volume, this patch puts the control granularity to the level
of volumes of the same type to minimize the impact of other Cinder parts.
In other words, the design is to bond QoS with volume types. So Cinder admin
can associate volume types with QoS specifications, and volumes of same volume
type share the same QoS specifications.
QoS can mean a lot different things that it's unlikely we can come up with a
interpretation that all vendors can agree on. So the approach this
implementation takes is to make Quality-of-Service specs as free-from, i.e.
expressed as key/value pairs.
Changes:
- Add a quality_of_service_specs table, using adjacency list relation to store
a specs entry and its detailed specs in key/values. Note that to be able to
distinguish where should the QoS specs be consumed, each QoS specs entity
will have a 'consumer' (i.e. fixed key) with the value of where admin would
like the QoS policy to be enforced/consumed, currently these three values are
considered valid: 'front-end' (Nova Compute), 'back-end' (Cinder back-end),
'both'. The default value for 'consumer' is 'back-end';
- Add a new API extension 'qos_specs_manage' to allow list/create/update/
delete/associate/disassociate of QoS specs;
- Add volume/qos_specs internal API for qos specs manipulation;
- Add 'qos_specs' info to data structure when
initialize_connection() is called.
- Add 'qos_specs' to request_specs and filter properties for
a volume create request.
TODO
- Modify 'type_manage' API extension to be able to accept qos info.
- Modify volume_types.create() to accept qos info and do the checks.

Dont crash service if sf cluster isnt available
Currently if the SolidFire driver is configured but the cluster
isn't available for some reason the ensure_export call will raise
an unhandled exception and crash the volume-service.
We should be able to handle things like loosing connectivity to
a single back-end without impacting the other volume-service
backends.
We'll wrap the ensure_export call in a try block here and
return None in the case that the connection can't be made.
This will keep the service from crashing and log an error
message that the connection timed out.
Additional work would include adding a periodic retry task
to the manager to try and start the backend service for us
on some regular interval incase the device comes back.
