Add an e2e test using the test web app, using a real deployment and call some/most of the servlets in an automated fashion

[ludoch]

The Dockerfile used by the App should be using the latest image built locally (that would mean a local docker build), or we would need to push a snapshot of the image in gcr.io

[ludoch]

We could also deploy most of the samples we have on github, again, using the latest snapshot image.

Steps:
1/ find good web apps to deploy (including the test app we have in this repo)
2/ find the urls we want to activate
3/ configure the Dockerfile to use a latest image built (will need to cover the 3 images java8, jetty9, compat)
4/ call mvn gcloud:deploy with the correct appid and appversion
5/ execute the urls access
6/ produce a dashboard so we can keep tests results (at least keep the logs on a gcs bucket?)
7/ host this on a Jenkins instance? We have one internally I could configure.
8/ anything else or better?

For 1, you can consider sample apps that we have for Managed VMs @JustinBeckwith might be able to point you to some apps. For compat, it might be good to have apps that exercise all/mostly used APIs.

Anything here should work :)
