Log messages about license files and probed locations are missing #238
Description
NServiceBus scans various locations for a valid license and outputs the location probed and the one selected.
All traversed locations and the scan result are logged (see https://docs.particular.net/nservicebus/licensing/#troubleshooting).
The instructions for troubleshooting are not working for the Functions package.
The issue stems from how the NServiceBus logger is adopted to Microsoft ILogger. This seems to be handled properly with NServiceBus.Extensions.Hosting by using a deferred logger factory that flushes all NServiceBus logs when an ILogger is available. A similar approach should be taken with the Functions package to allow license troubleshooting.
