Check if there are any v1alpha2 AWSCluster resources

[anvddriesch]

In Happa we have implementation for AWS clusters with API version - infrastructure.giantswarm.io/v1alpha2. We need to check if there are actually any clusters with such version, and if no, we should clean up the code.

todo

• [ ] For installations where the referenced API version (cluster.spec.infrastructureRef.apiVersion) doesn't match with the referenced resource's API version, check with AEs if we could update the referenced API version
• [ ] Once all the references are updated, then clean up the code in happa

Looks like it has also already been removed from apiextensions: https://github.com/giantswarm/apiextensions/pull/898

While there aren't any awsclusters with API version v1alpha2, some of the cluster resources still hold a reference to the old API version. Ideally they should be aligned, but as it is, this breaks how how we determine which provider resources to fetch in happa.

Installations where the referenced API version is mismatched with the actual resource's API version: akita anchovy anteater antelope argali bandicoot flamingo valkyrie viking visitor

I've reverted the changes with https://github.com/giantswarm/happa/pull/3877 in the meantime and updated the task list above.

@gusevda Can we close this issue? I don't think we want to invest in code cleanups for happa, right?

[gusevda]

Agree, closing it.
