A number of tests rely on SSH behavior but are not marked with
SkipUnlessSSHKeysPresent(). This means that the tests will run and
hang. This can be confusing for users because they may not know why
the tests failed. Instead, we should be reporting on the known issue
and skipping the test (hence why the helper Skip... function exists).
Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- audit-proxy
- crd-conversion-webhook
- entrypoint-tester
- inclusterclient
- iperf
- porter
- serve-hostname
This is part of the transition to using framework/log instead
of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
This fixes golint failures of framework/metrics_util.go.
Cleanup:
- SaturationTime was only used in test/e2e/scalability/density.go.
So this moves it into the e2e test.
- interestingClusterAutoscalerMetrics was not used in filterMetrics()
so this removes the related code.
