Attach agent information in communication to the server

[vikman90]

Parent Issue: https://github.com/wazuh/wazuh-agent/issues/241

When the agent registers, it must send information about itself to the server:

• IP address
• Operating system
• Agent version

This information must also be attached to the metadata headers in stateful and stateless messages.

Update

Working on new definition (new message structure). The structure of the registration request is still missing.
