Server's PeerConnectionCheckInterval not used in CheckPeerEndpoints

[EC2E-Gaulupeau]

Hi,
It seems that the CheckPeerEndpoints function doesn't use the server specified PeerConnectionCheckInterval, causing it to only use the default value of 15 seconds.

netclient/networking/client-ping.go

Line 100 in 13a39d5

PeerLocalEndpointConnTicker = time.NewTicker(PeerConnectionCheckInterval)

This should be like in watchPeerConnections

server := config.GetServer(config.CurrServer)
	if server == nil {
		return
	}
	if server.PeerConnectionCheckInterval != "" {
		sec, err := strconv.Atoi(server.PeerConnectionCheckInterval)
		if err == nil && sec > 0 {
			networking.PeerConnectionCheckInterval = time.Duration(sec) * time.Second
		}
	}
	autoRelayConnTicker = time.NewTicker(networking.PeerConnectionCheckInterval)
	defer autoRelayConnTicker.Stop()
