Neo 53889 adding abortable support

[infinity1013]

Description

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

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

@infinity1013 don't you think the docs should be updated for the usage of this feature? It should be added even in the best practises as well.
