Description

Ohai,

when trying to build plugin (e.g. foreman_remote_execution 5.0.0) in production, webpack fails to find the grapql-tag loader:

$ node --max_old_space_size=2048 /usr/share/foreman/node_modules/webpack/bin/webpack.js --config /usr/share/foreman/config/webpack.config.js --bail --env.pluginName=foreman_remote_execution
ModuleNotFoundError: Module not found: Error: Can't resolve 'graphql-tag/loader' in '/usr/share/foreman'

This prevents building plugins that need loaders for Debian.
This is not a problem for RPM builds, as there we force all NPM modules to be in the top-level /usr/share/foreman/node_modules.
This is not a problem in dev builds, because probably something is different between prod and dev :shrug:
