    Add HA feature gate and minVersion validation
    
    **What this PR does / why we need it**:
    
    As we add more feature gates, there might be occasions where a feature is only available on newer releases of K8s. If a user makes a mistake, we should notify them as soon as possible in the init procedure and not them go down the path of hard-to-debug component issues.
    
    Specifically with HA, we ideally need the new `TaintNodesByCondition` (added in v1.8.0 but working in v1.9.0).
    
    **Which issue this PR fixes:**
    
    kubernetes/kubeadm#261
    kubernetes/kubeadm#277
    
    **Release note**:
    ```release-note
    Feature gates now check minimum versions
    ```
