Description

I'm adding a tag to a metric, but when exporting it to influx db I can't see it anywhere

Steps to Reproduce

using OpenTelemetry;
using OpenTelemetry.Exporter.InfluxDB;
using OpenTelemetry.Metrics;
using OpenTelemetry.Trace;
using System;
using System.Diagnostics;
using System.Diagnostics.Metrics;

namespace Telemetry
{
	internal class Program
	{
		static void Main(string[] args)
		{
			const int sendMetricsFrequencyMilliseconds = 1000;
			TagList globalTags = new TagList
			{
				{ "TestTag", "Test tag value" },
			};

			using var meter = new Meter("TestMetric", null, globalTags);
			var counter = meter.CreateCounter<long>("test-counter");

			var metricsProvider = Sdk.CreateMeterProviderBuilder()
									 .AddMeter("TestMetric")
									.AddInfluxDBMetricsExporter(exporterOptions =>
									{
										exporterOptions.MetricExportIntervalMilliseconds = sendMetricsFrequencyMilliseconds;
										exporterOptions.Org = "-";
										exporterOptions.Bucket = "TestMetrics";
										exporterOptions.Token = "";
										exporterOptions.Endpoint = new Uri("http://localhost:8086");
										exporterOptions.MetricsSchema = MetricsSchema.TelegrafPrometheusV2;
									})
									.Build();

			counter.Add(10);
			metricsProvider.Dispose();
		}
	}
}

Expected Result

See added tag "TestTag" with value "Test tag value" in the influx db database.

Actual Result

No tag "TestTag"
