Feature/1271 improve shell parameterization in tests

[nerdvegas]

For tests that iterate over shells, we now get this:

test_build.py::TestBuild::test_builds_0_csh PASSED                       [  2%]
test_build.py::TestBuild::test_builds_1_tcsh PASSED                      [  3%]
test_build.py::TestBuild::test_builds_2_sh PASSED                        [  3%]
test_build.py::TestBuild::test_builds_3_bash PASSED                      [  3%]

Instead of this:

# iteration happened and printed to stdout, but we can't see it
test_build.py::TestBuild::test_builds PASSED                       [  2%]

Fixes #1271

Uses https://pypi.org/project/parameterized (which worked first time, good stuff).
