We have a number of errors in sentry from the frontend which receive an HTTP429 error from the API (too many requests) - search sentry for "You have exceeded your rate limit ". This seems to mostly happen in the importer, but also in the listen view and reports page.

We should update the API calls in the frontend to take care of this. Now that we have a single APIService it should be easy to centralise this.

There is already a small amount of code in the APIServcice that seems to try and handle this status, but it's not used in all requests.
