Minimum supported Node version is 6.9.0, but Object.values() was introduced in
Node < 7. Let's use a polyfill if needed.
This will be removed when minimum supported Node version is raised to 8.9.0.
Fixes#3459
When installing dependencies, npm informed us that measured had been deprecated,
and renamed to measured-core. Let's follow the advice, and get rid of the
warning.
npm WARN deprecated measured@1.1.0: This package has been renamed to
measured-core, all versions of measured have been re-released under
measured-core, please update your package and consider updating to the newest
version. See https://github.com/yaorg/node-measured for latest updates.
This package is used to expose a single endpoint ("/stats"), whose output does
not change after this commit.
Fixes#3458
