💪 Enhance logger providers configurations with separate logger providers

[stijnmoreels]

Is your feature request related to a problem? Please describe.
Currently, each testing framework logging package reuses the same CustomLoggingProvider to register the logger. This means that when the logger gets registered with the LoggerFactory.Create(...), one has to refer to the logger as "Custom" in the appsettings.json, when you use configurable logging, specific for logger providers.

Describe the solution you'd like
Create a dedicated logger provider for each test framework so you can refer to the name of the test framework in the appsettings.json instead.

{
  ...
  "Logging": {
    "Xunit": {
      "LogLevel": "Information"
    }
  }
}
