Description

Agent collects node processes in multiple classes:

CGroupsManager.java

NodeMemInfoCollector.java

NodeUsersCollector.java

The processes are collected by exec'ing OS 'ps ..' command and scraping the output.

Refactor to use a single helper class to collect process info and make it available as a list to the above classes. This would hide the algorithm for obtaining process info from client classes as well as remove duplicated code.
