Remote management communication over outbound connection

Improvements are implemented in the communication between the agent and the Repserver communication node to facilitate remote management by outbound connection. The WebSocket service (used as a persistent bidirectional channel between the agent and the repserver), starts and stays active during requests, avoiding connection blockages. In the event of a loss of network connectivity during a remote management outlet, the agent closes the communication channel after 5 minutes to ensure that the connection is successfully restarted, on the next remote connection.
