Add TBase and TEnum type adapter for JsonDataConverter

[nklijia2011]

These two adapters help supports having Thrift and TEnum data types in Java classes.

For class like the following.

class TestData {
    String val1;
    // TBase value;
    HistoryEvent val2;
    // TEnum value;
    EventType val3;
}

With the adapter:

{
  "val1": "test-thrift",
  "val2": "{\"10\":{\"i64\":321},\"20\":{\"i64\":1234567},\"40\":{\"rec\":{\"10\":{\"rec\":{\"10\":{\"str\":\"workflowType1\"}}},\"20\":{\"rec\":{\"10\":{\"str\":\"taskList1\"}}},\"30\":{\"str\":\"aW5wdXQ\"},\"40\":{\"i32\":11},\"60\":{\"str\":\"testIdentity\"}}}}",
  "val3": 11
}

Without the adapter:

{
  "val1": "test-thrift",
  "val2": {
    "eventId": 321,
    "timestamp": 1234567,

Add unit test?

[meiliang86]

This looks good to me btw.

Feel free to merge it into the master branch, as I don't have the permission to do that.

Made some additional change in JsonDataConverter.java

Now I removed the special handling in toData() and fromData() for the Thrift data type. As they can already be supported by the new TypeAdapter of TBase and TEnum.

Another reason I am doing that is: I want to pass thrift parameter for my activity function, and the current special handling for Thrift will cause issue for it.

For a single Thrift parameter
In serialization, it will call toData(), which is going to serialize the Thrift correctly.
In deserialization, it will call fromDataArray() instead of fromData(), which cannot deserialize Thrift correctly. And always return an empty Thrift message.

After this change, I can pass in any number of thrift message as activity parameters
