See #23

- use same server as normal test, but with an additional RPC handler
  that deliberately stalls before responding

- the timeout.sh test case does not work yet

- will use this later to update test scripts to run with sm transport

- move examples to tests
- leave one example in place and simplify it
- make sure everything works with cci
- update README.md to more clearly describe addressing and configuration with CCI

- makes cci/tcp work correctly with margo examples
