Create workflow to build packages

[AlexRuiz7]

Description

The new plugins for wazuh-indexer need to meet the requirements for the packages generation process (see https://github.com/wazuh/internal-devel-requests/issues/712). The plugins are self-compiled into a zip file by running the ./gradlew build command.

We need to generate the required GitHub Workflows to build packages for each of the plugins on demand. This tooling must be usable by wazuh-indexer's GitHub Workflow.

The goal of this issue, is to be able to generate a Wazuh Indexer packages with our plugins included. In order to do that, the wazuh-indexer build.yml workflow must invoke the build.yml workflow on this repository.

This repository will host several plugins under the plugins/ folder (see #4), so the plugin name needs to be an input parameter of the workflow. Once the plugins are successfully compiled, they are installed into Wazuh Indexer, as the rest of OpenSearch's plugins.

Implementation restrictions

• Use of GitHub workflow.
• Workflow is invoked from wazuh-indexer repo.
• Workflow is invoked manually.

Functional requirements

• The workflow receives the plugin name as a parameter
• Indexer's build workflow can opt out from building plugins (TEST variable is promoted to the workflow as build_plugins boolean parameter, defaults to true.

Plan

• Generate workflow to build plugins
• Edit wazuh-indexer's build.yml to invoke the plugin's workflow
• Edit the assemble.sh file to install the plugins
