Document disabling of session cookie for `request_loader` (#514)

* Document disabling of session cookie for `request_loader`

This change fixes the docs which earlier pointed to the now
'header_loader', in the section describing the process for disabling
session cookies for APIs.  It now correctly refers to the 'request'
related imports / other settings to achieve this.

* Add missing function to set 'login_via_request' to True
