- Added process to cleanup stale session affinity records

- 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.

Allow parameterization by environment in cluster/gce/config-test.sh
