Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration and test output

Special notes for your reviewer:
Testing passed for following tests:

~ make test-e2e LABEL_FILTERS=conformance
~ make list-e2e

Currently following tests fail due to version of the provider issues. we dont need this at this time as we only support v1beta1 when we release.

make test-e2e LABEL_FILTERS=clusterctl_upgrade

this one fails with following error
