[mod] NVM: dev-tools pre-installed in NVM's node installation

The Node.js installation in the NVM environment can be used by IDEs and other
developer tasks.  The required developer packagaes are added to the file
./.nvm_packages and will be installed when Node.js is installed.  Initial we
start with:

- eslint

Having a dedicated developer enviroment, provided by nvm makes it easy to
integrate Node.js packages into various IDEs.  One example is shown in the
.dir-locals.el which is used by emacs.
