Node.js 8.x on build server

Hi, as per #3320-meta could we please have a Node 8.x LTS release installed on WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/?
This will be needed for WordPress 5.0 & GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ (once merged) build scripts to operate.

Currently we have a 0.10.x & 6.9.x release available in the nodejs-base role.
