Nik Everett 5ef78fd015 Fix source filtering in reindex-from-remote (#22514)
Reindex-from-remote was accepting source filtering in the request
but ignoring it and setting `_source=true` on the search URI. This
fixes the filtering so it is piped through to the remote node and
adds tests for that.

Closes #22507
