Sticky Session Implementation
- Added process to cleanup stale session affinity records
- Automatically set cloud provided load balancer for sticky session if the service requires it - Note, this only works on GCE right now.
- Changed sessionAffinityMap a map to pointers instead of structs to improve performance
- Commented out cookie and protocol from sessionAffinityDetail to avoid confusion as it is not yet implemented.
