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.
