OTEL collector error logging is wrong

[zroubalik]

Otel logger is set as prometheus_server:

keda/pkg/metricscollector/opentelemetry.go

Line 19 in fb12330

var otLog = logf.Log.WithName("prometheus_server")

Also some error messages are printed with fmt.Println instead of using logger:

keda/pkg/metricscollector/opentelemetry.go

Line 110 in fb12330

fmt.Println("failed to register scaler metrics latency")
