//Support the current simple capacity check API besides the intent-based framework for backward compatibility. 
//If a cloud region does not support the policy-based interface, it is given a high net value assuming the current capacity api (yes/no) 
//returns an yes. This ensures smooth migration to the new policy-based framework.
