Update the elasticsearch version used in master
This matches the change going into 12.0 for omnibus gitlab-org/omnibus-gitlab!3331 (merged)
From omnibus MR:
We need gitlab-elasticsearch-indexer v1.2.0 in GitLab v12.0 . The list of changes in this version is here: gitlab-org/gitlab-elasticsearch-indexer!32 (merged)
CE and EE MRs to update the
GITLAB_ELASTICSEARCH_INDEXER_VERSION
file in gitlab are here: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/29237 and here: https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/13992 - but that only affects the tests at present.gitlab-org/release-tools!625 (merged) and gitlab-org/omnibus-gitlab!3276 (merged) will allow omnibus (and CNG too) to respect that file, but I've not had the chance to complete it in this milestone. So for now, we should just keep the versions in sync.
