Dan suggested as below for doc of A1 adaptor.

All our permanent project documentation is supposed to be in readthedocs format.  There is already an SDN-R documentation tree in ccsdk/features/docs/guides/onap-user.  It probably makes sense just to add the A1 adapter documentation there.

This ticket originally referred to Frankfurt release.
For Guilin release see CCSDK-2832  CCSDK-2500
For Honolulu a new ticket will be created.
