[FEAT] add tls to the coordinator server

[edwinkys]

Feature Description

We want to add TLS to the coordinator server which uses Tokio Tungstenite under the hood. Since coordinator server communicates with the dashboard, this allows a secured websocket connection to be established from the dashboard.

Potential Solution

Tokio Tungstenite should allow us to integrate this easily.

P.S. We want to make this functionality optional and not active by default.
