Description
Sometimes, the stream plugin may want to create/update its own global counters.
There is no way to do so currently.
One possible way to enable that is to use the stderr output of the stream process.
The stream process can emit the global counter update information (such as GLOCAL_COUNTER COUNTER_NAME NUM)
to the stderr of the process. The Stderr handling thread can call the global counter API whenever it encounters the global counter update information line.
