b7964a3c5a sma: forbid deleting devices with attached volumes
It makes it possible for stateless clients to send CreateDevice /
DeleteDevice each time a volume is attached / detached.  Deleting a
device with attached volumes results in FAILED_PRECONDITION error, which
a client can simply ignore.  The device will be deleted during the final
DeleteDevice call, once all volumes are detached.

We limit this behavior to device types that support AttachVolume /
DetachVolume methods, otherwise it would be impossible to delete such
devices.

c802dbe9fe sma: add device protocol name
A device can now be identified by a protocol and a name.  This allows to
have multiple types of devices providing the same protocol.  The
selection of which device manager to use for specific protocol will be
added in following patches.

048fb36ac3 sma: initial Storage Management Agent structures
Storage Management Agent is a gRPC server that provides an abstraction
layer above the SPDK RPC interface.  The interface aims to provide a set
of methods for managing various protocols (e.g. NVMe, virtio-blk) while
hiding the details of a particular transport.

The external API is defined by `lib/python/spdk/sma/proto/sma.proto`
protobuf file.  It defines the generic gRPC service methods and their
requests/responses.  Device-specific messages are defined in their own
files.  This patch also defines messages for creating NVMe and NVMe/TCP
devices.

This patch implements a gRPC service that delegates the work to a
specific device type.  A DeviceManager is a class that implements some
of the methods defined by the service for a given type of devices (e.g.
NVMe, virtio-blk, NVMe/TCP, etc.).  For now, only the RPC for creating a
device is implemented, others are added in subsequent patches.

The series implements the generic calls as well as their NVMe/TCP
implementation.  Support for other devce types could be easily added by
creating a new device manager and defining its protobuf parameter
definition.
