442 rev env


This change includes:
- endpoint for the client assets (brix lib compiled and css)
- Improved logging: 
  - changes in level 
  - added sequenceNodeKey or summary of sequenceNodeInfo
  - removed duplicate logging at different call stack (e.g. logged at IPS then also at controller)

I tested the error condition of unreachable CE (killing ce), and unreachable AMS (disconnecting from network)


@seann, could you code review.
Thanks.
