Update cost per action in QUOTA

The pricepkg action on the dappservices contract allows a DSP to set how much QUOTA to bill for per action. For example, a DSP could decide to charge 0.0002 QUOTA per vRAM warmup. The default for each action is 0.0001 QUOTA. The billable actions for all services may be found in the zeus-sdk/boxes/groups/services/SERVICE_NAME-dapp-service/models/dapp-services/SERVICE_NAME.json, for example: vRAM.
