The improvements to the REST API have been included into Patchew and are
deployed on http://patchew.org/.  They are not in use yet, pending more
work on authentication; this may be the topic of a future Summer of Code
internship.

Emanuele also converted several existing tests.  His framework was also
presented at KVM Forum 2019 by Laurent Vivier, Emanuele's mentor,  and
should be merged in 4.0.
