Adapt wazuh-metrics and data-visualizer CLIs to handle multiprocessing

closes #2258

Description

After adding multiprocessing to the Wazuh cluster and API, we needed some changes on the monitoring tools to keep track of all child processes.

Configuration options

• Wazuh metrics
  Configuration options remain the same. The CLI will look for all processes related to the given process name.

• Data visualizer
  Configuration options remain the same as we need to pass every CSV file to it. As child processes have a custom suffix, each CSV file will be considered as a different daemon.

Logs

• Running processes

  3 API processes and 3 cluster processes.

Tests

• Proven that tests pass when they have to pass.
• Proven that tests fail when they have to fail.

• Python codebase satisfies PEP-8 style style guide. pycodestyle --max-line-length=120 --show-source --show-pep8 file.py.
• Python codebase is documented following the Google Style for Python docstrings.
• The test is documented in wazuh-qa/docs.
• provision_documentation.sh generate the docs without errors.
