Allow environment variables to configure options #73
How would you recommend I approach the tests? I can either copy an existing test that tests functionality that relies on a boolean input option, or I can mock/spy within the scheme function and confirm that the cookie settings are correctly interpreted.
There are pros and cons to both: copying an existing test is easy, but not easy to scale and becomes a maintenance problem. mock/spy is not readily available because the server object passed to the scheme function is not the same server object that is supplied by the test (hapi uses a server._clone).
