Build nightlies of Node-ChakraCore

[joaocgreis]

Node.js on ChakraCore (https://github.com/nodejs/node-chakracore) is becoming increasingly stable. Hence, it is our intention to provide users with an easy way to start experimenting with the latest version, by providing experimental nightly builds. For now, this will include a Windows version and a Linux version build from the xplat branch.

If there are no objections, I will soon move forward with this. My current plan is to follow these steps:

• Skip the nodejs-nightly-builder step altogether (see next item).
• Create a new job in ci-release. It is not yet time to integrate with iojs+release, and it's better to have a dedicated job that can take any modifications or workarounds for now. This allows us to skip the nodejs-nightly-builder step above.
• Create https://nodejs.org/download/chakracore-nightly/ (staging + dist rootdirs)
• Add chakracore-nightly to promote_nightly.sh (+ settings)
• Open PR with Ansible changes to make the changes public. Does not need to land since this is not definitive. (Update: WWW changes for ChakraCore nightlies and releases #547)

Please let me know of any suggestions.

nightly builds seem reasonable to me.

I'd like to see this end up in the nightly job at some point, but having it separate to speed up development makes sense.

Windows nightly releases are already in place. However, Linux releases cannot be built out of our current release servers, because the xplat branch requires a more recent OS and some dependencies.

In order to disturb or current infra as little as possible, I plan to create a new release server with Ubuntu 16.04 only for ChakraCore. I accept full responsibility for maintaining it (@orangemocha can be a backup if absolutely necessary). @nodejs/build any objections?

Ubuntu release server done, deployed using JaneaSystems@8c8d28c . Will follow with a OS X server if there are no objections.

OS X server deployed using https://github.com/nodejs/build/tree/master/setup/osx and brew install cmake icu4c. Nightlies available for Windows, Linux and OS X: https://nodejs.org/download/chakracore-nightly/v7.0.0-nightly20161129efeaf88f0c/

Node-ChakraCore has reduced external dependencies, so OSX nightlies are now being released from the OSX release server.

Node-ChakraCore now supports Ubuntu 14.04. Deployed a Ubuntu 14.04 release server to replace 16.04 with JaneaSystems@622ea30 .
