Collector OpenSearch exporter failing due to too many requests

[julianocosta89]

Just to keep track on the demo issues as well, I've opened the following issue in the OTel Collector Contrib:
open-telemetry/opentelemetry-collector-contrib#31343

The following message keeps popping up in the collector logs:

2024-02-20T13:37:08.758Z	info	exporterhelper/retry_sender.go:118	Exporting failed. Will retry the request after interval.	{"kind": "exporter", "data_type": "logs", "name": "opensearch", "error": "{\"type\":\"cluster_block_exception\",\"reason\":\"index [otel] blocked by: [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block];\",\"caused_by\":{\"type\":\"\",\"reason\":\"\",\"caused_by\":null}}", "interval": "26.169887369s"}
