Sling Servlet Resolver's cacheSize must be set to 0 to prevent "this session has been closed" exceptions for scripts.
Added two versions of a sample bundle and two versions of a sample script. Setup script now uploads them when run and creates the /content/mynode node. To be rendered by the script, it must be accessed at http://host:port/mynode.test.
Orchestrator should make sure proxy is stopped initially.
