title: How to read .ENV values in Karate
body: <p>I'd like to remove secrets from my karate-config.js and place them in a .ENV file (which is in the .gitignore). That way I can run the Karate tests on various environments (local and Azure Devops pipelines) and only have to set the right environment variables.</p>
  <p>The only thing is that I can't find a way to read the properties set in the .ENV file. <code>java.lang.System.getenv('MY_KEY')</code> returns null, while <code>java.lang.System.getenv('PATH')</code> does return the expected data.</p>
  <p>Currently I've created a karate-base.js and merge in a secrets.js via a <code>karate.merge('secrets.js)</code>, but that's sub-optimal because I still need a file with secrets (passwords/keys) which I want to eliminate.</p>
