Issues identified in network tests

[kthare10]

• log for handlers in process pools sometimes get lost
  • To address this, pass only log config to the handler and create logger object within the process pool. Issue was sharing logger object with the parent process doesn't work always
• defunct zombie processes were left by ansible scripts in the AM
  • this is a known ansible playbook executor issue. recommended solution is to run the parent process as init so it can reap the zombies
• Update documentation to include architecture diagram and thread model for AM
