[OCPCLOUD-1988] Migrate AWS to out of tree cloud provider

[JoelSpeed]

This PR migrates the AWS cloud provider from in-tree to out-of-tree. It must be merged in tandem with the PR for KCMO and CCMO to avoid a build that contains one or the other operator PRs without the other. If either merges without the other, it will either lead to no cloud controllers or duplicate cloud controllers, either of which will not work well.

Note the AWS cloud provider code has been removed from K8s in-tree in 1.27, this must merge in 4.14.

• KCMO PR
• CCMO PR
• Tested with Cluster Bot
• Origin PR

CI results looks good (linked in description) though with some flakes, I think this should be good to go. Will monitor CI results for AWS over the next few days to check stability.

as in prior runs, a payload containing all the changes will bootstrap and upgrade successfully. The manual verification across PRs is green. I'm button merging these to ensure we don't get a payload that is missing some of the changes.
