Upgrade to HA control plane

Promote a single-master cluster to a 3-master highly available control plane. The flat HA fee starts accruing once enabled.

On a pay-as-you-go cluster the flat HA fee simply starts accruing. On a subscription cluster the API charges the pro-rated HA fee to the saved payment method (balance first) and raises the monthly price; in the dashboard the upgrade goes through checkout.
