added cms_query_rewrite.tmpl which was not added into git in earlier commit/pull

it had to go along with commit 74c6963b386496c6e9bc9197ec9f383e7a760599 in https://github.com/dmwm/DAS/pull/4051

the only impact of this template being missing is if user types/clicks on an  "almost valid" DAS query, but fields in greps do not exist the query rewrite suggestion will not show: "Template cms_query_rewrite not known".
