Default CacheConfiguration instance can't be serialized

[Nikolay Izhikov]

Hello, Guys.

I found that CacheConfiguration which implements Serializable contains not
serializable fields by default.

CacheConfiguration -> affMapper -> CacheDefaultBinaryAffinityKeyMapper ->
proc -> CacheObjectBinaryProcessorImpl.

Is this a bug or I miss something?

Simple reproducer:

```
public class SimpleSerializableTet extends GridCommonAbstractTest {
    public void testRemoteFilterFactoryClient() throws Exception {
        Ignite g = startGrid(0);

        IgniteCache<Object, Object> cache =
g.getOrCreateCache("TEST_CACHE");
        CacheConfiguration ccfg =
cache.getConfiguration(CacheConfiguration.class);

        assertTrue(ccfg instanceof Serializable);
        assertTrue(ccfg.getAffinityMapper() instanceof Serializable);

        try (ByteArrayOutputStream bos = new ByteArrayOutputStream()) {
            ObjectOutput out = new ObjectOutputStream(bos);
            out.writeObject(ccfg);
            out.flush();
        }
    }
}

```
Exception is:

```
java.io.NotSerializableException:
org.apache.ignite.internal.processors.cache.binary.CacheObjectBinaryProcessorImpl
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)
```

Hi Nikolay,

It is strange, because Cache Configuration is saved under
StoreConfiguration into persistent store cache_data file.

Did you find an anwser?

Sincerely,
