Acceptance: Check exit codes when applying manifests
Acceptance: Check exit codes when applying manifests

Prior to this commit, any failures that occurred
when manifests were applied during acceptance setup
would be logged, but the test run would (incorrectly)
continue.  This commit checks the exit codes more
explicitly so that the runs should fail sooner when
this occurs.
