cloud kms signer

example:

```go

	ctx := context.Background()

	client, err := kms.NewKeyManagementClient(ctx)

	if err != nil {

		log.Fatal(err)

	}

	signer, err := cloudkms.NewSigner(client, "projects//locations//keyRings//cryptoKeys//cryptoKeyVersions/")

	if err != nil {

		log.Fatal(err)

	}

	rootCa := &x509.Certificate{

		SerialNumber: big.NewInt(1),

		// TODO: fill

	}

	data, _ := x509.CreateCertificate(rand.Reader, rootCa, rootCa, signer.Public(), signer)

	cert, _ := x509.ParseCertificate(data)

	// Sign

	msg := "hello, world"

	h := signer.HashFunc().New()

	h.Write([]byte(msg))

	digest := h.Sum(nil)

	signature, err := signer.Sign(rand.Reader, digest, crypto.SHA256)

	if err != nil {

		log.Fatal(err)

	}

	// Verify Signature

	if err := cert.CheckSignature(cert.SignatureAlgorithm, []byte(msg), signature); err != nil {

		log.Fatal(err)

	}
