Interim work on open-ended grading acceptance testing POC

lms/djangoapps/courseware/features/openended.feature

+Feature: Open ended grading
+  As a student in an edX course
+  In order to complete the courseware questions
+  I want the machine learning grading to be functional
+
+    Scenario: I can submit an answer for instructor grading
+    Given I am registered for course "MITx/3.091x/2012_Fall"
+    And I log in
+    And I navigate to an openended question
+    When I enter the answer "I have no idea."
+    And I press the "Check" button
+    Then I see the grader status "Submitted for grading"
+    And I see the grader message "Feedback not yet available."
+
+    Scenario: I can submit an answer for instructor grading
+    Given I am staff for course "MITx/3.091x/2012_Fall"
+    And I log in
+    And I navigate to an openended question
+    When I submit the answer "I love Chemistry."
+    And I visit the staff grading page
+    Then my answer is queued for instructor grading
