A configuration change is an array of sum types that each describe a configuration change. Sometimes the configuration can be the empty type, in which case the PEMs should attempt to set the value to a default that is maybe platform-specific. We will add to this list of possible changes over time but this is a good first set. Differential Revision: https://phabricator.services.mozilla.com/D195146
