This test could flake if the load balancer hostname was provisioned but is not yet resolving in DNS from the test process.
The fix is to retry this step for up to 5 minutes.

This test could fail when the cluster was under heavy load. This could cause kubectl to emit "Throttling request took [...]" logs that triggered a failure in the test.
The fix is to ignore these innocuous warnings.

We had this code that printed out pod logs when certain tests failed, but it is a bit cumbersome. We're removing it because we added a CI task that exports all pod logs after every CI run, which accomplishes the same thing and provides us a bunch more data.

We've seen some test flakes caused by this test. Some small changes:
- Use a 30s timeout for each iteration of the test loop (so each iteration needs to check or fail more quickly).
- Log a bit more during the checks so we can diagnose what's going on.
- Increase the overall timeout from one minute to five minutes

In the case where we are using middleware (e.g., when the api group is
different) in our kubeclient, these error messages have a "...middleware request
for..." bit in the middle.

This test could flake in some rare scenarios. This change adds a bunch of retries, improves the debugging output if the tests fail, and puts all of the subtests in parallel which saves ~10s on my local machine.

This test has occasionally flaked because it only waited for the APIService GET to finish, but did not wait for the controller to successfully update the target object.
The new code should be more patient and allow the controller up to 10s to perform the expected action.

This new capability describes whether a cluster is expected to allow anonymous requests (most do since k8s 1.6.x, but AKS has it disabled).
This commit also contains new capability YAML files for AKS and EKS, mostly to document publicly how we expect our tests to function in those environments.

At the end of the test, wait for the KubeClusterSigningCertificate
strategy on the CredentialIssuer to go back to being healthy, to avoid
polluting other integration tests which follow this one.
We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.
Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.
