What this PR does / why we need it:
we are seeing tests fails in local dev environments with macOS 12:

Panic [0.458 seconds]
[BeforeSuite] BeforeSuite
/Users/cerobert/go/src/sigs.k8s.io/cluster-api-provider-azure/controllers/suite_test.go:48

  Test Panicked
  unable to start control plane itself: failed to start the controlplane. retried 5 times: timeout waiting for process etcd to start successfully (it may have failed to start, or stopped unexpectedly before becoming ready)
  /Users/cerobert/go/src/sigs.k8s.io/cluster-api-provider-azure/internal/test/env/env.go:107

which is caused by etcd failing to start up

Hi @zmalik. 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.

Thank you. I have verified it. This fixes the issue.
Also, does this mean that the etcd binary that was causing the issue was built on go 1.10 or before?

does this mean that the etcd binary that was causing the issue was built on go 1.10 or before?

looks like kubebuilder-tools@1.16.4 was using etcd 3.3.11 which was build on go 1.10.3

looks like there might have been a collision in random RG naming?
