forward alertmanager logs to ES
Part of: https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/13770
In our fluentd-elasticsearch chart, we generate regexes for matching container log filenames from the name parameter in this config. This change: !439 (merged) started forwarding all logs from containers that contain prometheus
in their name. However, it turns out that alertmanager containers have promethe
in their name. As a result, the other change didn't actually result in alertmanager logs being forwarded.
This MR targets alertmanager specifically.
