Allow auto-creating users

[rshaw-mcs]

Optional workaround for the requirement to have pre-defined users in the accounts.json file. CF Access has policy control, so no need to whitelist here. Haven't fully tested the condition of one user with multiple emails, but I think it should work with existing logic.

There may be a better way to do this, just remove the accountService checks altogether instead of working around it. This would be more of a straight through proxy for all users to the oidc provider service, but it wasn't obvious how to do that.

Up to you if you'd include this as an option, but it was the workflow I was looking for.

Hey @rshaw-mcs , thanks for the contribution!

The PR is looking great, just please adjust the comments so that they are more clear what are they supposed to do

Oops, I pushed some other commits related to a different feature to this PR, need to remove those. My bad

Thanks! Last thing, could you re-run npm install and push new package-lock.json? I am getting some unused packages. If you will get the same result, which version of node & npm are you using?
