DIV-3491 - create DN case for integration testing (#1)

* WIP: over to Hosain

* DIV-3491 - included missing require and removes `this` reference

Also ignored idea files

* Organising dependencies

* Reusing test method between DN and AOS cases

* DIV-3491 - rethrow error if there is an issue creating a case

* DIV-3491 - create case should get caseData instead of file path

* Addressed comments from code review and added Travis CI files. Also added test case and adjusted tests after changes were made to source code.

* Using resolves for returning a promise from Sinon
