Auth command

[filip-debricked]

Adds initial auth command with 3 subcommands:

• login (authenticates the user by opening debricked.com and sending back token and then saving credentials locally)
• logout (removes saved credentials)
• token (returns the saved credentials, if they exist, and refreshes credentials if needed)

In the future the other CLI commands which needs a token will use the saved credentials if a token is not specifically provided.

This is the initial version of the command, and there will be some changes to the backend before we can utilise it fully.

Just a few suggestion after checking out the OAuth2 package docs 🙂

I think this looks excellent now! I hereby declare you an OAuth2 professional :).
