Currently when there are no resources available the error message we return is a bit verbose and could be a bit worrying for users (the default error message from httpx tells users to go to https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/503 for more info, which is a bit confusing).
This PR introduces 2 custom exceptions, APIError for general HTTP errors and NoResourcesAvailable for when a pipeline has not scaled up. This makes the error messaging nicer and also allows the user to use these exceptions in their own code.
