// The substitutions do two things:
// 1. Filter the response to just templates matching the te* pattern
//    so that we only get the templates we expect regardless of which
//    templates exist. If xpack is installed there will be unexpected
//    templates.
// 2. Create some templates to expect in the response.

The API returns the following response:
