Use Case

With procstat plugin it's not possible to know the CPU consomation for master processes for exemple.
In the procstat liste, there is no information about level of child.
It's important to avec different tag to use agregators.

Expected behavior

Add child_level :

procstat,filter=/usr/sbin/httpd-root,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.2552110254764557 1730221495000000000
procstat,filter=/usr/sbin/httpd-root,parent_pid=3899854,child_level=1,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.6878506392240524 1730221495000000000
procstat,filter=/usr/sbin/httpd-root,parent_pid=3899854,child_level=1,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.6878506392240524 1730221495000000000

Actual behavior

procstat,filter=/usr/sbin/httpd-root,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.2552110254764557 1730221495000000000
procstat,filter=/usr/sbin/httpd-root,parent_pid=3899854,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.6878506392240524 1730221495000000000
procstat,filter=/usr/sbin/httpd-root,parent_pid=3899854,process_name=httpd cpu_usage_sum=0,memory_usage_sum=0.6878506392240524 1730221495000000000
