use blocking function to shut down etcd/apiserver
While using testutil.TestDir in a project to run unit tests against a local kube-apiserver, I noticed that I was building up orphaned etcd and kube-apiserver processes on each test run. This seems to be because the use of context to signal a shutdown in SetupEnvTest doesn't block the exit of the go process, thus fails to process environment.Stop(). The simple solution seemed to be to just send an anonymous function back as the cancel function, rather than the context cancel function.
Tested locally to confirm that unit tests depending on this still ran successfully, and no etcd/kube-apiserver processes were left behind.

Hi @mlsorensen. Thanks for your PR.
I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.
Once the patch is verified, the new status will be reflected by the ok-to-test label.
I understand the commands that are listed here.
