Investigate the need of increase TimeoutStartSec in wazuh-indexer service

Wazuh version	Install type	Action performed	Platform
4.3.9-1	Wazuh indexer	Start	Deb/RPM

An error was reported starting the Wazuh indexer:

job for wazuh-indexer.service failed because a timeout was exceeded

This is commonly due to not enough host resources (either not enough total CPU/RAM or available CPU/RAM). The service tries to start the process but this one is taking longer than foreseen.

The service variable TimeoutStartSec determines the timeout of starting the process. Increasing this value could allow starting the service in those hosts with resource limitations.

Tasks

• Determine why the current value was set to 75.
• Investigate Opensearch and Elasticsearch values.
• Investigate the pros/cons of increasing this value.
• If the investigation concludes with increasing value, change the code.
• Test with the older package and limited host, reproducing the error. Then, test the new one that results in a started service.
