SDK should support abortable requests

Currently there is no way to abort a request from the client. For example:

1. UI makes requests to fetch the data
2. While the call is in progress, the UI component unmounts/redirects to some other component.
3. While un-mounting, the UI should be able to cancel pending HTTP calls to avoid unnecessary attempts to re-render.

No files, tests, or entry points are identified in the issue. Start by tracing how the SDK creates HTTP requests, then determine how a client could cancel pending calls; done means the UI can abort an in-progress request when its component unmounts or redirects.
