SpdkCsiInitiator defines interface for NVMeoF/iSCSI initiator - Connect initiates target connection and returns local block device filename e.g., /dev/disk/by-id/nvme-SPDK_Controller1_SPDK00000000000001 - Disconnect terminates target connection - Caller(node service) should serialize calls to same initiator - Implementation should be idempotent to duplicated requests.

SpdkNode defines interface for SPDK storage node - Info returns node info(rpc url) for debugging purpose - LvStores returns available volume stores(name, size, etc) on that node.
