This adds two new flags to "pinniped get kubeconfig": --skip-validation and --timeout.
By default, at the end of the kubeconfig generation process, we validate that we can reach the configured cluster. In the future this might also validate that the TokenCredentialRequest API is running, but for not it just verifies that the DNS name resolves, and the TLS connection is available on the given port.
If there is an error during this check, we block and retry for up to 10 minutes. This duration can be changed with --timeout an the entire process can be skipped with --skip-validation.

This makes output that's easier to copy-paste into the test. We could also make it ignore the order of key/value pairs in the future.

The thing we're waiting for is mostly that DNS is resolving, the ELB is listening, and connections are making it to the proxy.

All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.
This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".
In impersonator_config_test.go, instead of waiting for the resource
version to appear in the informers, wait for the actual object to
appear.
This is an attempt to resolve flaky failures that only happen in CI,
but it also cleans up the test a bit by avoiding inventing fake resource
version numbers all over the test.

- Use `Eventually` when making tls connections because the production
code's handling of starting and stopping the TLS server port
has some async behavior.
- Don't use resource version "0" because that has special meaning
in the informer libraries.
This time, don't use the Squid proxy if the cluster supports real external load balancers (as in EKS/GKE/AKS).

Because otherwise `go test` will panic/crash your test if it takes
longer than 10 minutes, which is an annoying way for an integration
test to fail since it skips all of the t.Cleanup's.
This updates our issuerconfig.UpdateStrategy to sort strategies according to a weighted preference.
The TokenCredentialRequest API strategy is preffered, followed by impersonation proxy, followed by any other unknown types.
