Allow enable calico floatingIPs feature

[MatthieuFin]

Hi,
I am upgrading our network plugin Calico from v3.21 to v3.22. But since v3.22.2 floatingIPs feature is disabled by default in Calico due to a vulnerability.
We need this feature to advertise our "public" outgoing IPs from some pods. To mitigate the vulnerability we are using OPA Gatekeeper to whitelist our allowed pod to advertise authorized IP addresses.

Unfortunately kubespray don't support to specify this option, so for now i have to manually override this value after kubespray run. I whish to add this value support directly in kubespray Calico plugin role.
