title: Protractor: how to make the configuration file more flexible?
body: <p>I have an idea to make my configs more flexible. For example I have 10000 config files with same parameters:</p>
  
  <pre><code>seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['C:/Users/Lilia.Sapurina/Desktop/Protractor Tests/Scenarios/ps-grid-column-filter-range_spec.js'],
  params: {'url_filter': 'http://wks-15103:8010/ps/ng-components/examples/ps-grid-column-filter-range.html'}
  </code></pre>
  
  <p>And once I want to change path to specs, html or change selenium address. Can I do this in another file for all my configs?</p>
  
  <p>For example write in my config:</p>
  
  <pre><code>seleniumAddress: '../Variables/seleniumAdress.txt'
  </code></pre>
  
  <p>Or maybe exist another interesting ways to solve this problem?</p>
