✨ Adds MaxIPs to OpenstackFloatingIPPool

[bilbobrovall]

Adds MaxIPs to OpenstackFloatingIPPool, after the pool has claimed that amount it will no longer create new floating IPs.

Relates to #1750 and solves a use case we have where we're preallocating entire ipranges, and we don't want random IPs if the pool is depleted. Our usecase could probably be solved by using cluster-api-ipam-provider-in-cluster for those clusters but we probably want to be able to control how many IPs a pool allocates anyways.

Hi @bilbobrovall. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
