Title: [#75804242] Add flag to print usage information 

The `-help` flag is overridden by `go test` and doesn't display the available flags, so add a new `-usage` flag that displays usage information (including flags).

Also, use the default usage function when `-edgeHost` is supplied with an empty string.
