Migration to OpenSearch's Debian scripts

[AlexRuiz7]

Description

On #527, we detected that we were using different Debian packages scripts made on our own, instead of using these from OpenSearch present in the repo, These include compatibility to systemd, service and other service managers.

Moreover, it may benefit from other feature such as removing configuration files on apt purge.

The goal is to migrate our changes and use these Debian packages scripts, removing duplicated code.

Functional requirements

• The wazuh-indexer deb packages use the scripts from upstream
• The wazuh-indexer deb packages scripts don't miss any functionality from the scripts currently in use.

Implementation restrictions

• Inputs and outputs of the assemble.sh must not change.

Plan

• Update the assemble.sh script to use the scripts on distribution/packages/src/common.
• Port the required changes from distribution/packages/src/deb.

Related issues

• Wazuh-Indexer service script not executable on SysV init #602
• Wazuh-Indexer SysV Init script fails to start the service #603

Update assemble.sh script to use the OpenSearch packaging scripts for the Debian system, the build process gives no errors, but when the package is installed using dpkg it crashes

dpkg -i wazuh-indexer_5.0.0-0_arm64_706df02e-c5121c7-3e0ef45.deb 

dpkg-deb: error: archive 'wazuh-indexer_5.0.0-0_arm64_706df02e-c5121c7-3e0ef45.deb' uses unknown compression for member 'control.tar.zst', giving up

The assemble tool requires the .deb packaging scripts to be stored in a debian/ directory, by modifying the temp directory where the scripts are stored the package can be built and installed correctly again.

sudo dpkg -i wazuh-indexer_5.0.0-0_arm64_9fb8d0c6-c5121c7-3e0ef45.deb

Anyway it fails at the startup, seems to be a problem with the permissions, probably the owner user or group is not being properly configured

For the .rpm packages, it requires further development on the assemble tool since currently it uses a .rpm.spec file as packaging script, and it must be replaced with the Debian like scripts made by OpenSearch for both cases.

For some reason, the DEB maintenance scripts are passing through the upgrade process instead of the install causing the installation to be incomplete.
