Summary: This separates the babel config of the local-cli and the packager from the one used by the transforms of the packager since it doesn't run in the same environment and the local-cli/packager doesn't require react specific transforms and runs in node 4 so we can also avoid some es2015 transforms that node already supports. I had to move the code in cli.js so it can still run in node 0.12 that doesn't support `const` since it is no longer transformed. **Test plan** Run the local-cli on node 0.12 and there should be a message saying that it requires at least node 4. Run the local-cli on node 4 and 5 and everything should work the same as before. I was also hoping for some perf gains but there was nothing noticeable. I did benchmark the babel-register call and it stayed pretty much the same. As for runtime performance it can help if there are optimisations for es2015 features in node.
