fn: reorg agent config (#853)

Browse Source 
* fn: reorg agent config

*) Moving constants in agent to agent config, which helps
with testing, tuning.
*) Added max total cpu & memory for testing & clamping max
mem & cpu usage if needed.

* fn: adjust PipeIO time
* fn: for hot, cannot reliably test EndOfLogs in TestRouteRunnerExecution
