Explain requirements for certificate auto-generation
Update Installing, Configuring, and Running the Open edX Platform to explain that with regard to certificate auto-generation, it
requires setting a Waffle switch,
does not apply to enrollments in the audit and honor tracks.
In addition, update the Building and Running an Open edX Course guide with a back-reference to the former, to clarify that certificate auto-generation for self-paced courses does not work out of the box in an Open edX configuration, and instead requires the aforementioned Waffle switch.
