Implement "remember me" for OAuth-based login.

- Pass a `remember_me` query parameter along with the initial OAuth request, and
  pick this parameter up during the omniauth callback from
  request.env['omniauth.params']`.

- For 2FA-based login, copy the `remember_me` param from `omniauth.params` to
  `params`, which the 2FA process will pick up.

- For non-2FA-based login, simply call the `remember_me` devise method to set
  the session cookie.
