Update gitlab-elasticsearch-indexer to v1.3.0
This is another update of gitlab-elasticsearch-indexer to match the GITLAB_ELASTICSEARCH_INDEXER_VERSION
file in gitlab-ce+gitlab-ee, following the form of !3331 (merged) .
Just like that MR, I still haven't managed to finish release-tools!625 (merged) and !3276 (merged) yet
