cmd/k8s-operator,k8s-operator: add topology spread constraints to ProxyClass (#13959)

Browse Source 
Now when we have HA for egress proxies, it makes sense to support topology
spread constraints that would allow users to define more complex
topologies of how proxy Pods need to be deployed in relation with other
Pods/across regions etc.

Updates tailscale/tailscale#13406
