Add before/after methods to workflow interceptor.

[mfateev]

WorkflowInterceptor lacks methods that are invoked before the workflow is started and after it completes.

They might be necessary to inject appropriate thread local variables.

Hello Maxim, Is there any posibility to create the start and after interceptor in the current version? We want to add our status custom logic in these point.

Thanks

The current interceptor is far from ideal, but should be Ok for your use case: https://github.com/uber/cadence-java-client/blob/d56612f05108efd4696310935d99def3a794f915/src/main/java/com/uber/cadence/worker/WorkerOptions.java#L174
