Implement account-less new user flow

• The documentation does not make it clear that a user must actually log in to obtain the Dockstore CLI client
• The instructions when setting up a new account are not clear. The Setup page says to
  1. download and execute a script and follow its instructions
  2. THEN copy and past the token into ~/.dockstore/config. When the script is run, it asks if I’ve set up an account. Since I’m in the middle of the process, I answer “N” (because I haven’t completed account setup, just half-way through - or at least that’s what it looks like to me), and the script exits. I then proceed with step (ii) and re-run the script. When I re-run, it is NOT interactive like it was the first time (it prints its own help text and then simply exits) - but there is no explanation of this change in behaviour.
• It is hard to find the link back to download the CLI tool again. “Setup” is not intuitive.

Maybe there should be a big ad/image on the front page that says “Get started today!!” with a direct link to download the dockstore CLI. Then they should be prompted for account creation if they don’t have one - but is an account even really necessary if they are just interested in playing with CWL/Dockstore capabilities locally on their workstation?

As an update for who works on this ticket, many users just use a dummy token with success but this needs documentation
