Support for manually entering OAuth tokens

[Sjlver]

Hi,

it would be great if there was a way to manually specify OAuth tokens. Otherwise, a number of things (two-factor authentication, or enterprise auth (see #384)) don't work.

This can be accomplished in a number of ways:

• document somewhere (other than here) the format of the ~/.config/hub file
• read the OAuth token from an environment variable
• provide a new command (e.g., hub set-token) that prompts the user for the token

Thanks!

These are valid suggestions, thanks. However, two-factor auth is already fixed in master (release imminent!), and web-based OAuth process for Enterprise is more problematic than just figuring out where to inject the token since it requires you to create an application for hub in your Enterprise installation, then use that application's credentials to start the OAuth process.

I might provide this feature as part of a new command proposed in #225, so I'm closing this as a dup of issues referenced in this thread.
