Follow-up from #226 where @prajwalkumar83 has reported:

I have the same problem as my environment (like most corporate servers that sit behind a firewall) does not have internet access. I have downloaded esrally and its dependencies from PyPi and installed esrally successfully. How do i run tests in offline mode by downloading the required test files offline? the --offline option does not help as the tracks still need internet access. Any suggestions/workarounds?

While #226 focuses on simplifying installation of Rally in these cases, we'll tackle the issue reported above in this ticket.
