Add reconnect capability to agent-simulator

[AdriiiPRodri]

Description

Due to the recent development of Agents reconnect, we need to add the reconnect capability to the agent simulator. This new functionality will allow us to perform several tests necessary to verify the correct functioning of Agents reconnect.

We need to replicate the behavior of the Wazuh agents when they receive the HC_FORCE_RECONNECT (force_reconnect) command, in order to replicate the loss of connection with the manager and the reconnection to the same manager or a different one (depending on the load balancer configuration).

Current behavior

Agent-simulator does not have the capability to reconnect when requested from a manager.

Expected behavior

Agent-simulator is able to receive and correctly process (close the connection and establish it again) the reconnection request.

I'm reopening this issue to further investigate why the agent-simulator sometimes fails to reconnect.
