E2E tests didn't catch govmomi connection error as cannot validate certificate

[zhanggbj]

What happened?

This is a error caught when running CAPV E2E tests but not in CPI E2E tests.

CPI: https://github.com/kubernetes/cloud-provider-vsphere/releases/tag/v1.32.0-beta.0

CAPV test: kubernetes-sigs/cluster-api-provider-vsphere#3250

What did you expect to happen?

Investigate if CPI can catch this kind of error in tests and improve e2e tests.

How can we reproduce it (as minimally and precisely as possible)?

Run CAPV E2E test using
CPI: https://github.com/kubernetes/cloud-provider-vsphere/releases/tag/v1.32.0-beta.0

CAPV: https://github.com/kubernetes-sigs/cluster-api-provider-vsphere/releases/tag/v1.12.0-beta.0

Anything else we need to know (please consider providing level 4 or above logs of CPI)?
