I'm trying OpenTelemetry client with Elastic APM to log into Elastic APM server. There are several instrumentations that exists both in OTEL client and Elastic APM client, for example `AspNetCoreInstrumentation`. Do these do the same thing? Do I need to use both or either of them?

Sample:

```auto
services.AddOpenTelemetry()
                .ConfigureResource(resource => resource
                    .AddService(serviceName))
                .WithTracing(tracing => tracing
                    .AddSource(serviceName)
                    .AddAspNetCoreInstrumentation()); // <--

...
hostbuilder.UseElasticApm(new AspNetCoreDiagnosticSubscriber()); // <--

```

Hi, @deastr.

Generally, you'd choose one agent that best suits your needs. Both support similar instrumentations, although equally, both have some unique support right now. You can see what Elastic APM .NET agent supports [here](https://www.elastic.co/guide/en/apm/agent/dotnet/current/supported-technologies.html). We also have some features such as central config, span compression etc. which are not part of OTel.
