Use the digital ocean API to snapshot each week.

Reference: https://developers.digitalocean.com/documentation/v2/#snapshots

We are anyway maintaining one snapshot, we might as well keep that up to date. As the API is a REST API, figuring it out should be easy.

The script will look at the status of the wiki and a couple of random (pre-defined) pages and if all of them are returning 200 responses, then it will snapshot the present wiki and delete the old snapshot.
