Fix hub URL validation

          Description

          Validating trackhub URLs is currently done in the browser and involves making requests for their content and ensuring that it conforms to the UCSC trackhub specification. The UCSC CORS policy does not allow websites to make these requests, however. Implement a work-around.

          Possibilities:

          • See if the UCSC API can be used to validate a trackhub.
          • Implement a validation endpoint on our hub facade API.
          • Use a public CORS proxy to forward browser requests.

                I was able to find a UCSC API endpoint that can be used to validate track hubs. Please see my changes here.

                I tested this with both track hubs in UCSC public list as well as others that I found online e.g.

                Confirmed that the example URL and others are functioning as expected. Moving to Closed.

                I spoke too soon. The track hub site referenced is on localhost. Looking into it.

                Hard reload in my browser fixed the problem. Playbooks working as designed. For future reference: a line in trackhubs.js containing:

                const BACKEND_DOMAIN

                gets changed.
