[TIMOB-15728] CLI: Add some diagnostic capabilities for setup/info

we are having a number of challenges in certain complex IT environment that use SOCKS, HTTP Proxies, blocked outbound websites, etc. we need to add something either to setup or info (or maybe a specific command?) that will perform a series of tests to attempt to reach our systems. it would be good as well to have this also dump out any whitelisted IP / hostnames we depend on so that an administrator could easily give that to their NetOps people. (this would suggested by a customer recently). This would include not only the CLI but Titanium SDK and Studio, etc. we should hit NPM, api.appcelerator.net, Tistudio update service, etc with a test request and validate that we can use those services correctly in the environment the CLI is running.
