duplicate functions in connection and rpc package

[Madhu-1]

I see below functions are present on both connection and rpc package

func GetDriverName(ctx context.Context, conn *grpc.ClientConn) (string, error)

func GetPluginCapabilities(ctx context.Context, conn *grpc.ClientConn)

func GetControllerCapabilities(ctx context.Context, conn *grpc.ClientConn) (ControllerCapabilitySet, error)

func ProbeForever(conn *grpc.ClientConn, singleProbeTimeout time.Duration) error 

func probeOnce(conn *grpc.ClientConn, timeout time.Duration) 

func Probe(ctx context.Context, conn *grpc.ClientConn) (ready bool, err error) 

is this intentional or do we need to remove duplicate functions and make use of a single package?
if we need to remove it. I can do it.

I think we should remove the functions from connection
