Fix connection bugs

[Neylix]

Description

Fixes some bug in connection between nodes:

• Add a timeout in tcp handle_connect. Default timeout is infinity so the process stay stuck in this function if the server is unreachable.
• If a node changes it's ip, the connection module associated to the node is not notified. Now whenever a node is updated, if the connection informations change (ip, port, transport), the connection process is killed and a new one is started with the new informations

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Run 3 nodes
• Stop one and restart it with other port parameter

Connection should be updated and nodes can contact each other
