Use gcloud for deployment of java apps

[mgenov]

As application deployments with appcfg are no longer supported it is valuable gcloud to be used and for java apps to ensure that Java apps could be deployed on GAE.

Addresses the following issue with appcfg:

Application deployment failed. Message: Deployments using appcfg are no longer supported.
