SSL support on the Local SDK run?

[ludoch]

A customer is testing a MVM app written in Java. When using the old dev server, SSL configuration (https://cloud.google.com/appengine/docs/java/config/webxml#Secure_URLs) is ignored locally, but when using gcloud preview app, the SSL configuration is not ignored, which leads to difficulty testing.

Desired state is that when running gcloud preview app, the app should ignore the SSL settings to be consistent with the current dev server.
