What this PR does / why we need it:
Currently deploying a cluster using an explicit proxy doesn't work ever since 2.13.0 was released.

Which issue(s) this PR fixes:

Fixes #6108

Special notes for your reviewer:
Previously the no_proxy.yaml would unset the http_proxy, https_proxy, HTTP_PROXY and HTTPS_PROXY variables due to ansibles DEFAULT_HASH_BEHAVIOR setting being set to replace rather than merge. A combine would make it so it works regardless of what the hash behavior setting is set to.

Does this PR introduce a user-facing change?:

NONE

Hi @codyseavey. 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.
