Add a more compact representation of usage stats.
We are replaceing the package name in the activity name with a * iff the activity is in the
same package, otherwise the activity name is pritned out in full.
This small change will remove a lot of bytes (in the order of kilobytes for a real log) from the logged data on the network and downstream processing,
since the package name is repeated in almost all cases.
An exampe of the new format is here:
