Obsolete NServiceBus.Logging in favor of Microsoft.Extensions.Logging

[ramonsmits]

Describe the suggested improvement

Is your improvement related to a problem? Please describe.

NServiceBus.Logging exists in all versions of Core. Its a logging abstraction by NServiceBus that is from the time the .NET ecosystem didn't have a defacto abstraction. Now that Microsoft.Extensions.Logging has matured there is no reason for NServiceBus users to use its abstraction.

This also fixes issues with NServiceBus.Logging.LogManager being a service locator pattern and any loggers created could conflict when multiple endpoints are hosted in a single process

Suggestion

Mark all public types in NServiceBus.Logging with [Obsolete]with guidance to transition toMicrosoft.Extensions.Logging`

Currently abstraction blocks certain refactorings like:

• Introduce an AddNServiceBus extension method on IServiceCollection NServiceBus.Extensions.Hosting#519

@jbogard asked if we have an overview of all categories like:

• https://learn.microsoft.com/en-us/ef/core/logging-events-diagnostics/simple-logging#message-categories

When we eventually will move away from our limited abstraction it would be nice if such an overview could be added (or even auto generated) in our docs.
