api event is missing the stage property

[holygrolli]

Using aws-serverless-java-container to run a Spring application in a Lambda function I was continuously getting errors.

How to reproduce?

1. Checkout and build the Spring example.
2. run with sam local start-api -t sam.yaml (latest release and latest develop build)
3. run curl http://localhost:3000/pets and get {"message":"Gateway timeout"}

What causes Gateway timeout?

It is caused by a Java NullPointerException at spring-web-4.3.9.RELEASE-sources.jar!/org/springframework/web/util/UrlPathHelper.java:245 originating from org.springframework.web.util.UrlPathHelper#getPathWithinApplication because com.amazonaws.serverless.proxy.internal.servlet.AwsProxyHttpServletRequest#getContextPath requires the stage be set. When I understand the events correctly (and the event generator supports my assumption) then the stage property must be set

How to fix

I added the fixed string prod to the events stage property. I assume for aws-sam-local there is no need for other stages.

Thanks for this, and thanks for the test case to go with it.
