Design and development of the communicator module for the new agent

[TomasTurina]

Description

As part of the development of the new agent MVP, it is necessary to develop a new communicator module.

Take into account the following:

• Use the POC developed as a model to develop this MVP.
• Integrate with the wazuh-http-request library.
• The module should be able to:
  • Register with the manager.
  • Request a token (authenticate) from the manager.
  • Send stateless and stateful messages to the manager.
  • Receive commands from the manager.
• Use the concurrency control module for task scheduling.

For more considerations (including API endpoints), see the spike issue.
