Framework support for node e2e.
This should let us port existing e2e tests to the node e2e suite, if the tests are node specific.
generic pod-per-node functionality for testing - 2 node test only
- update framework to decompose pod vs svc creation for composition.
- remove hard coded 2 and pointer to --scale
- rebase: ForEach only on Running pods
- add waitFor step in guestbook describe and wrapper
- simplify logs in polling, make panic immediate, give rolluped stats in
the logs.
Improve logging for failure on ForEach
