Support authentication for vscode .devcontainer

[floitsch]

When using vscode .devcontainers, the authentication is not stored, and it's necessary to copy/paste a login url from vscode to a browser for every deploy.
Would be nice to save some kind of token as a file to handle login.

I have attached a starting point for a .devcontainer. However, the toit CLI fails rather hard after logging in using the browser.

I'm not sure what the problem is. It looks like it could actually be the login that is the problem. So my first thought that it wasn't saving login info may be caused by the login not ever really happening.

Anyway, a working .devcontainer environment would still be nice to have.
