WHY IT NEEDS A POLICY

Why configure_ha_for_host needs a policy

This tool performs infrastructure configuration rather than data destruction. It modifies HA (High Availability) parameters on CloudStack hosts, affecting resilience and failover behavior. While configuration changes are significant and impact system behavior, they are typically reversible through reconfiguration. This places it in Write rather than Destructive or Execute.

From the tool's definition configure_ha_for_host - 'Configure HA for host' modifies host-level high-availability settings, which alters infrastructure state persistently but reversibly.
