An example web service that allows a snap that has been downloaded (usually via snap download)
to be installed. The service listens on http://localhost:5000 and needs the restricted
snapd-control interface to be connected.
Download a snap and copy the file and assertion to /mnt. Then run:
curl http://localhost:5000/snap-name/snap-revision
For example:
snap download chuck-norris-webserver
sudo cp chuck-norris-webserver_16.* /mnt/
curl -v http://localhost:5000/chuck-norris-webserver/16
Snapd installations are asynchronous, so installation will not occur immediately.
