Ryan Ernst ef3b954f63 Scripts: Convert template uses to return String instead of BytesReference (elastic/x-pack-elasticsearch#1279)
This is the xpack side of elastic/elasticsearch#24447. The one caveat is
there are a number of places within the xpack api that use
BytesReference to pass down to templates. These are convert to encode
into a BytesArray when necessary, so as not to require changing all of
those apis here at once, but they should all be convert to String as
well.
