From the code itself:
deprecated command line options for essex compatibility. To be
removed in Grizzly release cycle.
so this patch removes these deprecated env vars that have been
moved into the OS_* namespace since Folsom, and updates the tests
that probably should have been using the non-deprecated option
anyway :)
The fact these are still in there are causing some confusion,
we actually had a bug report over in docs claiming OS_SERVICE_TOKEN
should be replaced with SERVICE_TOKEN!
