// CONSOLE
// TEST[s/templates/templates\/template*/]
// TEST[s/^/PUT _template\/template0\n{"index_patterns": "te*", "order": 0}\n/]
// TEST[s/^/PUT _template\/template1\n{"index_patterns": "tea*", "order": 1}\n/]
// TEST[s/^/PUT _template\/template2\n{"index_patterns": "teak*", "order": 2, "version": 7}\n/]
// 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:
