MVP Indexer refinement (I)

[havidarou]

Description

We want to iterate and polish the MVP indexer so we can test the overall design of the solution.

Currently, we have identified the following improvements:

• wazuh-indexer 5.x packages are sent to the S3 bucket for 4.x packages #491
• Remove Filebeat compatibility setting from opensearch.yml #499
• Initialize Commands Index from Indexer Setup plugin wazuh-indexer-plugins#122
• Enrich index templates with agents' information #525
• Nest ECS Host fields under Agent #539
• Events generator for 5.x indices #518
• Index templates refinement I wazuh-indexer-plugins#147
• Review index templates, documentation and events generators are synced
• ECS host field removal from stateful indices #570
• Commands / orders batching wazuh-indexer-plugins#157
• Command manager timeseries index model #565
• The CM plugin fails to send orders back to the Management API wazuh-indexer-plugins#154
• interface fields are missing at inventory-networks index root level #571

[Under analysis] The default opensearch.yml file contains node-1 as default node name, and the certificates are named indexer. I believe we should use the same name: node-1. So we prepare this better for a cluster environment.

Won't do. We might revisit this later in the future.
