Describe the bug
OtlpMetricsExporterService uses io.opentelemetry.exporter.otlp.metrics.OtlpGrpcMetricExporter internally. But does not expose configuration values for e.g. headers and temporality.
Thus, it is not possible to e.g authenticate against a basic auth secured OTEL Collector.
Expected behavior
It is possible to configure headers and temporality for OtlpMetricsExporterService
