perf app tuning

[ludoch]

Looking at the perf branch

1/ not sure you need appengine-web.xml since you have app.yaml
https://github.com/GoogleCloudPlatform/jetty-runtime/blob/feature/perf/perf/perf-server/src/main/webapp/WEB-INF/appengine-web.xml

2/ the app.yaml should use env:flex instead of vm:true which is deprecated (and possibly a slower request path)

Thanks for reviewing.
I changed that
It looks with this change we cannot see anymore the number of instance in console.cloud.google.com ? Compute Engine / VM Instances.

Thanks!

That would be a regression in the console for Flex? Mike: ideas?

You should be able to see Flex instances under App Engine / Versions or App Engine / Instances.
