Description

After a job is submitted, it might need some configuration change, specifically it might need more containers. In SAMZA-704 a tool is being added to write to the coordinator stream. This tool can be used to write new configurations to the coordinator stream. However, another tool (ConfigManager) is needed to read the config changes and react to them, which is the goal of this task. This tool should be brought up after the job is submitted and read any config changes added to the coordinator stream, and react to each accordingly.

Each configuration will need a different action, and the should be added one-by one.
