Add e2e testing of cloud provider via Cluster API Clusterctl framework or Cluster API kubetest2 deployer

[randomvariable]

What would you like to be added: Add e2e conformance testing to this repo

Why is this needed: Discussed a while ago about testing requirements for this repo, and had demo'd launching kubetest via Cluster API's clusterctl framework. Inclusion of conformance testing is almost complete (see https://github.com/kubernetes-sigs/cluster-api/pull/3652), and am considering adding a Cluster API deployer to kubetest2 ( https://github.com/kubernetes-sigs/kubetest2/issues/48 ).

This could be used to then set up e2e testing on this repo.

https://github.com/kubernetes-sigs/cluster-api/pull/3652 is in, and https://github.com/kubernetes-sigs/cluster-api-provider-aws/pull/1991 serves as an example to consume, so can probably start adding similar here.

Will probably naively try spinning up Cluster API AWS cluster with external CPI, pass the kubeconfig to a new goroutine to run the CPI and then run the relevant kubetest bits.

Hah, I started playing around with a kubetest2 deployer, but @benmoss is already ahead in https://github.com/kubernetes-sigs/kubetest2/issues/48#issuecomment-708675720
