Support timeout in wait for signal APIs

New features

• Supports the timeout in all "wait for signal" APIs. Related ticket

Breaking changes

• IWorkflowItem.Resume APIs signature has changed. Originally you could have resume a waiting item as below

[Signal]
public WorkflowAction Cancle(WorkflowSignalEvent @event)
{
  Lambda("BookOrder").Resume(@event.SignalName)
}

but now have to pass the event object in "Resume" API.

[Signal]
public WorkflowAction Cancle(WorkflowSignalEvent @event)
{
  Lambda("BookOrder").Resume(@event)
}

• Polling strategy function signature has changed. Originally you would have written the custom polling strategy as below

 var taskList = new TaskList("my-list");
  taskList.ReadStrategy = MyCustomStrategy
 ...
 private static async Task<DecisionTask> MyCustomStrategy(Domain domain, TaskList taskList, 
                                 string pollingIdentity, CancellationToken token)
{
   var decisionTask = await domain.PollForDecisionTaskAsync(taskList, pollingIdentity , token);
   return decisionTask
}

But with this release you will write as below:

 var taskList = new TaskList("my-list");
  taskList.ReadStrategy = MyCustomStrategy
 ...
 private static async Task<WorkflowTask> MyCustomStrategy(Domain domain, TaskList taskList, 
                                 string pollingIdentity, CancellationToken token)
{
   var decisionTask = await domain.PollForDecisionTaskAsync(taskList, pollingIdentity , token);
   return WorkflowTask.Create(decisionTask);
}
