Problem: both SIGQUIT_ETCD_AND_REMOVE_DATA_AND_STOP_AGENT and test.sh
will attempt to stop agents and remove directories.
Solution: since test.sh creates directories and starts test, it should be
responsible for cleanup.

- Use go testing infrastructure, such that logs are printed only in
case of failure.
- Split the test into multiple sub-round and sub-round-testcases such
that tree of execution reflects the logic.
- Use 'development' loggers that are formatting the output to be human
readable.
