OpenstackServer controller is not watching IPAdressClaim resources

[MisterKind]

/kind bug

What steps did you take and what happened:
When using an OpenstackFloatingIPPools in an OpenstackMachine, an IPAddressClaim is created which will create a floating ip in Openstack.
However currently the OpenstackServer controller do not watch the IPAddressClaims it create, which stuck the provision of the server.

Here an extract of logs showing that the OpenstackServer is not reconciled until I manually add an annotation on it at 10:01

What did you expect to happen:
Reconcile the OpenstackServer when the IPAddressClaim is ready.

Anything else you would like to add:
