Fluentd now sends logs directly to OpenSearch node IPs instead of using
a Load Balancer. This change reduces Load Balancer overhead from high
log volumes. The Load Balancer for OpenSearch remains in place, as it
is still used by OpenSearch Dashboards. Fluentd continues to handle node
availability, automatically distributing logs via round-robin, ensuring
log delivery even if individual OpenSearch nodes become unavailable.
Fixed Fluentd configuration template to avoid generating unnecessary
empty lines when optional parameters are not set.

This avoids the need to use a proxy, or some other means, to connect to
Prometheus. This is disabled by default and can be enabled by setting
enable_prometheus_server_external to true.

This change replaces ElasticSearch with OpenSearch, and Kibana
with OpenSearch Dashboards. It migrates the data from ElasticSearch
to OpenSearch upon upgrade.
No TLS support is in this patch (will be a followup).
A replacement for ElasticSearch Curator will be added as a followup.
