As part of the MakeVM port, it was requested that this be pursued as a stretch goal.

After having spent some time with RAPI, aside from some niggly details around network interfaces, I believe that for example reimplementing gnt-instance wouldn't be too terribly complicated. RAPI is fairly low level but it maps largely to the params to the command line.

Upside of this is that python3-ganeti-rapi is already in stretch-backports.

Here is the REST API documentation for future reference: http://docs.ganeti.org/ganeti/2.9/html/rapi.html
