this small series tries to smooth out the transition to HttpOnly cookies
for our users:

- cookies are now removed by the server if a 401 UNAUTHORIZED error is
  encountered. this matches the behaviour of our previous javascript
  browser-based clients. it is necessary, as they can't remove the
  cookie themselves anymore due to the new security measures.
- log-in is possible again, even if an invalid HttpOnly cookie is
  provided.
- `Expire` is removed from the cookies to make them "session cookies"
  again. this should restore security assumptions some users may have
  made about closing their browser and being logged out. note that
  session cookies may still be restored after a browser was closed, if
  the browser uses session restoration.

proxmox:

Shannon Sterz (3):
  rest-server: remove auth cookies via http header on unauthorized
    request
  auth-api: don't set `Expire` for HttpOnly cookies anymore
  auth-api: allow log-in via parameters even if HttpOnly cookie is
    invalid
