Implement websocket reconnect

[FabioRosado]

On v1 we have a reconnect method that is triggered when we lose connection or when we change the websocket URL. We should implement a similar thing in v2.

For reference:

  reconnectToWebSocket() {
    if (this.active_connection && this.active_connection.connected) {
      this.active_connection.close();
    }
    if (this.connectionTimeout) {
      clearTimeout(this.connectionTimeout);
    }
    console.log(`Reconnecting in ${this.connectionCooldown} seconds.`);
    this.connectionTimeout = setTimeout(this.connectToWebsocket, this.connectionCooldown * 1000);
    this.backoffCooldown();
  }
