Daniel Canter b5e1b8f619 Use t.Run for /pkg/cri tests
A majority of the tests in /pkg/cri are testing/validating multiple
things per test (generally spec or options validations). This flow
lends itself well to using *testing.T's Run method to run each thing
as a subtest so `go test` output can actually display which subtest
failed/passed.

Some of the tests in the packages in pkg/cri already did this, but
a bunch simply logged what sub-testcase was currently running without
invoking t.Run.
