When parsing the privileges, we now no longer throw an exception if
there haven't been any names parsed out. This is not an issue though,
because we validate that the `names` array is not empty when we parse
it, and that it's not `null` before returning from the function.
Adds a rest test that sends things out of order to test this still
works.

Original commit: elastic/x-pack-elasticsearch@62a38bea8f
Template support is going to be removed from the Search API to its own Search Template API in the lang-mustache module (see elastic/elasticsearch#17906, elastic/elasticsearch#18765). This commit changes Watcher's SearchInput and SearchTransform classes so that it now uses a WatcherSearchTemplateRequest that contains both the search request and the template. Search request and template are rendered using WatcherSearchTemplateRequestService before being executed.
