Subject BinaryObject API confuses users
Date Fri, 06 Dec 2019 10:17:29 GMT
Hello, Igniters.

We have confusing API in `BinaryObjectBuilder` class.

The code below leads to the `ClassCastException`
The cause is java method resolution rules [1]

> There may be more than one such method, in which case the most specific one is chosen

I suggest to deprecate `setField(String name, @Nullable BinaryObjectBuilder builder);` method
and introduce 
`setBinaryField(String name, @Nullable BinaryObjectBuilder builder);` instead of it.

What do you think?

public class BugTest extends GridCommonAbstractTest {
    @Test public void testBinaryObject() throws Exception {
        try (Ignite ignite = startGrid(0)) {
            BinaryObjectBuilder builder = ignite.binary().builder("testVal")
                .setField("name", "John Doe", String.class);

            builder.setField("name", builder.getField("name"));
