Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 6.4.0

• Cross-platform modules:

• Android Runtime:

• iOS Runtime: 10.15

• Plugin(s):

• Node.js: 12.18.3

• Please, attach your package.json and webpack.config.js as these configurations are usually critical for investigating issues with webpack

Describe the bug
I'm building a nativescript-vue app
I'm unable to read environment variables passed from the command line when using the nativescript CLI.
Inside of webpack.config.js I expect to be able to do a console.log(env) and see the variables I've passed to the tns run command printed out.

To Reproduce
tns run ios --device 'iPhone 11' --env.server_url=localhost:3000

Expected behavior
// webpack.config.js

module.exports = env => {
 console.dir(env); // { server_url: 'localhost:3000' }
}

Sample project

Additional context
Ultimately my goal is to be able to pass the variables to DefinePlugin so that In can access them in Vue application.
Note -- I understand that webpack.DefinePlugin will simply do a textual replace of the value provide.
