Spike to create a parallel_test type that optionally pulls test_suffix from env variable.
moving test_suffix around so the glob only only pulls in the files we are interested in.  this reduces the number of files that need to be grep'd downstream.
taking env type changes and applying it to the test type so it can now run minispec tests
converting test_suffix to regex and moving test file selection back into a grep call
finish converting test_suffix to regex and adding tests for different runners
Merge pull request #261 from centro/env-configuration
