OpenID Support (progress tracking)

After discussion we decided to do it in the following way:

• Redirect to a static page under this app for now, but the redirected page should be general, i.e. be able to handle all NDN namesaces instead of specific ones. The information of applied namespace should be passed via the state parameter.
• The redirected page parses the search parameters and bounce all state back to the application. We plan to use Push API to do this notification.
• Plan to use NDNts ndn-cert server if ndn-cxx is too hard to modify.

There will be another repo storing NDN cert related part.

Issue: this works fine in offline mode, but the SW cannot properly serve the cached file.

We have setup the NDN-Cert server: https://github.com/tianyuan129/ndncert-oidc
The deployed app worked in our test. Consider this as done.
