What this PR does / why we need it:
This PR introduces an until/retry with a task that fetches binary to ansible host[running kubespray] from k8s master nodes

Which issue(s) this PR fixes:

Recently while testing the k8s upgrade with kubespray v2.14.2, I had faced below mentioned issue on my platform.
TASK [kubernetes/client : Copy kubectl binary to ansible host] ***************** Friday 09 July 2021 20:53:23 +0000 (0:00:00.400) 0:15:48.785 *********** [0;31mAn exception occurred during task execution. To see the full traceback, use -vvv. The error was: OSError: [Errno 26] Text file busy: b'/usr/local/bin/kubectl'[0m [0;31mfatal: [m1-kms0001.mgmt.oiaas]: FAILED! => [0m [0;31m msg: Unexpected failure during module execution.[0m [0;31m stdout: ''[0m

By the error it seems that binary is used at the time of execution of this task and hence upgrade process terminated, I have introduced an until/retry to tackle such error and try to fetch binary for at least 20 attempts before terminating the upgrade process.

I am open to suggestions for improvising this task, so as to avoid termination of k8s upgrade due to this task.

Hi @Smita8081. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
