Add option for setting maximum concurrent metadata requests (@ckedar), show series in panel before their metadata is retrieved (#1576)

* Show series in Study Browser before their metadata is retrieved * Switch to decreasing for loop after code review (thanks @ckedar!) * feat: Limit concurrent series metadata requests (#1581) * Limit concurrent series metadata requests * Switch to decreasing for loop after code review (thanks @ckedar!) * Set default maxConcurrentMetadataRequests to unlimited and add explaination of setting in config Co-authored-by: kedar.netelixir <kedar.choudhary@netelixir.com> Co-authored-by: Erik Ziegler <erik.sweed@gmail.com> * Address comments from code review * Comment out misbehaving test Co-authored-by: Kedar <ckedar@gmail.com> Co-authored-by: kedar.netelixir <kedar.choudhary@netelixir.com>
