Add a gen_server wrapper for launching erlang ports and testing riak_ensemble.
ensemble_only_test is an eqc test that spawns five erlang nodes in ports and sets up a riak ensemble cluster using those 5 nodes. It uses the ensemble_basic_backend and implements all riak_ensemble_client operations. It does not currently do any nasty things beyond shutting down nodes. It's unknown how useful tests like this are for testing riak and riak_ensemble as a system, considering riak itself and the riak_kv_ensemble_backend include safety properties that the basic backend does not. Namely cluster membership transitions wait for data handoff before membership changes. In such cases riak_tests are the preferred way of testing. However, for others hoping to use riak_ensemble standalone (without Riak) this test can provide some working examples.

Add a parallel EQC test that launches 5 nodes using erlang ports and tests riak_ensemble without any of the riak bits. See individual commits for more details.
