EX-8016 lipe: Identify lfs command issued by lamigo

Each shell command issued by lamigo on OSS is identied
by attached comment. For example,
"lfs mirror extend -N ...  > /dev/null 2>&1 # lamigo testfs-MDT0000"
This can help identify the source of the command and track down
a reason why we have too many command running concurrently.
