Convert auto-generated repo-controller test to use gocheck

[pavannd1]

Change Overview

• The auto-generated tests used BDD-style Go testing framework. This also led to some third-party modules being direct dependencies and causing issues in compilation of the tests.
• Converted the test to use gocheck like the rest of Kanister and added support for running it in our environment.
