Node e2e test fixes:

- Improve documentation and method naming
- Fix command this is run remotely
- Never reschedule the busybox logging test pod since it is supposed to terminate
- Update log test condition retrylogic to correctly retry instead of failing the test
- localhost -> 127.0.0.1 to work on coreos
- give name to etcd to work on coreos
- allow using full hostname for nodename for coreos
