Log4Net Appender cannot connect using ConnectionString

[dirthsj]

Is your feature request related to a problem? I have an older .NET Framework application I am adding application insights to. However, when creating an ApplicationInsightsAppender instance I am only able to specify InstrumentationKey.

Describe the solution you'd like. I should be able to provide a ConnectionString instead of an InstrumentationKey

Describe alternatives you've considered. Using InstrumentationKey ingest until this is fixed.

Additional context. N/A

Microsoft is moving away from the instrumentation keys: https://learn.microsoft.com/en-us/azure/azure-monitor/app/migrate-from-instrumentation-keys-to-connection-strings

Besides that, you want to be able to use the complete TelemetryConfiguration object, if you need to use Managed Identities for instance.
