Install the latest Node.js 8.x LTS release on the "build" server

[netweb]

With WordPress 5.0 release focused on Gutenberg, Gutenberg requires the Node.js 8.x LTS release.

As such adding Node.js 8.x to the "build" server will be required.

WordPress 5.0 will also utilize this Node.js 8.x LTS release for its build tools

At the time of creating this ticket, the latest Node.js LTS release is 8.9.3 ​https://nodejs.org/en/

Other than the node version, are there any other changes that might be needed to ensure that WordPress 5.0 & Gutenberg (once merged) builds continue smoothly?

Gutenberg now has the following explicit requirements:

• ​https://github.com/WordPress/gutenberg/blob/master/package.json#L13-L15

    "engines": {
      "node": ">=8.0.0",
      "npm": ">=5.0.0"
    },
  

Gutenberg has no known further requirements to be installed on the build server to build WordPress 5.0 with Gutenberg at this stage.
