Add the -upmLogFile parameter

Unity Tools for Azure DevOps - Feature Request

Please describe your feature request

Since version 6000.x it is possible to add the -upmLogFile parameter:

Specify the path and file name where Unity writes the log file for the UPM background application, which runs independently of the Editor. You can specify -upmLogFile and -logFile in the same command. If you include both arguments, you can specify independent paths for the two log files.

In the same way we would have to expose an output variable called upmLogFilePath.

This is good idea and fairly easy to add. I'll add it in the next release.
