StdCallbackContext for replay deduping. Now developers do not need to
provide a name when calling services. There is a unique call graph
context maintained for each service call made. The context is request
aware, so different requests made will have their own independent
context for dedupe

Dedupe identical requests

```java
   ProgressEvent<Model, StdCallbackContext> result =
      initiator.translateToServiceRequest(m -> createRepository)
         .makeServiceCall((r, c) ->
            c.injectCredentialsAndInvokeV2(
                r, c.client()::createRepository))
         .success();

   ProgressEvent<Model, StdCallbackContext> result_2 =
       // make same request call
       initiator.translateToServiceRequest(m -> createRepository)
           .makeServiceCall((r, c) ->
              c.injectCredentialsAndInvokeV2(
                r, c.client()::createRepository))
           .success();

   assertThat(result).isEqualsTo(result_2);

```

- Remove handshake mode
- Adding wait strategy that can be changed, defaulting to re-schedules with
  no local waits for Lambda binding
- changes unit tests to reflect removal of handshake mode, fixed unit
  tests for serialization errors
