Attempt to reduce provider lifetime issues

[cijothomas]

Have seen users not managing the provider lifetime correctly. Partly because of copy-paste from console example: https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/docs/metrics/getting-started/Program.cs#L28, to other workloads like ASP.NET, without changes.

This also adds a log, so self-diag can offer some hints about the issue, in some situations.

Late to the 🎉, but LGTM.

An additional thought might be to include some lifetime guidance in some of the XML comments. Maybe on the Create*ProviderBuilder methods? https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/src/OpenTelemetry/Sdk.cs#L57-L74

I could take a stab...
