New CI job to look for changes in lock files

With MDL-63346 already integrated and the policy accepted and enabled, it's time to create a new job in the CI servers to, continuously, look for new lts (lts/carbon) releases leading to problems. From the original issue:

TODO: A job @ CI servers will be, daily, using latest lts/current version to detect if there are lock ( package-lock.json or npm-shrinkwrap.json) changes. It will fail when that happens and inform integrators. Jumps to lts/next will be detected manually (unless can be done automatically and warn about it).

That's it, ciao
