readline: add support for the AbortController to the question method

In some cases a question asked needs to be canceled. For instance
it might be desirable to cancel a question when a user presses
ctrl+c and triggers the SIGINT event.
Also an initial empty string was set for this.line since the
cursor methods fail if line is not initialized.
Added custom promisify support to the question method.
