[pve-devel] [PATCH v2 1/3] ship proper nodejs module 'pve-eslint'

[Dominik Csapak <d.csapak@proxmox.com>]

instead of concatenating the eslint module into our app.js, ship
a 'pve-eslint' module that exports the built eslint module

to do this, we have to leave the module type on 'umd' instead of
changing to 'var' so that nodejs can properly import it.

 Subject: [PATCH] adapt webpack config
 
-changes to 'var' from 'umd' since we want to use it in the same file
 adds 'cli-engine' to build (we use it in our wrapper)
 and target 'node' since we will use it on the cli
