Detailed steps to reproduce the problem?

The current implementation of handshake in the Go driver is missing the following spec compliance:

All strings provided as part of the driver info MUST NOT contain the delimiter used for metadata concatenation. Drivers MUST throw an error if any of these strings contains that character.

The Go driver is not compliant. You can repro with the following:

func TestMGC_Client_SetDriverInfoWithDelimeter(t *testing.T) {
	opts := options.Client().SetDriverInfo(&options.DriverInfo{
		Name:     "has|pipe",
		Version:  "1|2",
		Platform: "p|q",
	})

	client, err := mongo.Connect(opts)
	defer func() { _ = client.Disconnect(context.Background()) }()

	require.Error(t, err)
}

Output on master:

❯ go test -run TestMGC_Client_SetDriverInfoWithDelimeter -v -failfast

Definition of done: what must be done to consider the task complete?

Determine if we can validate while construct client options. If not, document to the user not to do this and silently drop the pipes.
