Ensure that pods coming from the unit test configuration validate,
and that proper names are generated.
Lowercases source filenames, strips all but a-z0-9, and tests
for consistent results.
Currently all commands are being build with extra flags. The extra
flags appear because of a direct import of the testing package from
the fake_etcd_client.go source file.
Remove the direct import of the testing package. Add a tools.T
interface to support existing behavior. Also clean up two TODO items
by remove using of the expectError and expectNoError functions.
Fixes#579
