title: xUnit test results export to TestRail
body: <p>I've got Selenium automation tests using C# with xUnit test framework.
  When the tests are run the results are generated into a xUnit standard XML file.
  I am looking at the ways to somehow import the results from XML file into the TestRail so that I have a central repo for all test runs and I can generate meaningful reports inside TestRail.</p>
  
  <p>I know there's an API I can use but creating methods inside the tests to post each test result is looking very cumbersome. 
  Instead it would be really great if I can import the XML file into TestRail.</p>
  
  <p>Please help.</p>
