removed "for instructor" text and added reserves_config isites_tool_url to production.py
Require penzance canvas_sdk in base requirements (for now while version is still considered 'dev').  Add SDK request context settings to environment files.  Set up an instance of the RequestContext at the module level in views.py for the manage sections tool.
Default a missing canvas token to None when building SDK settings for environments.

Added logic to remove test student from section enrollments and to ensure that the count excludes test student.
Added TEST_STUDENT_ROLE to settings to enable filtering by role
Moved the role vale to settings
Added test cases for utility ‘get_enrollments_without_test_student’. SInce the backend call that fetches the enrolled was moved to the utility, had to fix some of the existing test cases to use this utility
