[Feature Request] Sample request: Entity/long-running workflow with continue as new and signal handling

[cretz]

Describe the solution you'd like

Create a sample workflow that is long-running and continues as new, and make sure it has some processable signals that do something like run an activity so we can show waiting for outstanding ones to complete and signal carryover via workflow input.

@cretz have a look at the SlidingWindow example in my baching PR #175 . I am not sure this has everything you were asking for, but maybe it helps. There are also tests for this example that might also help prove compatibility with what you need.
