[Extensibility Request][Subscription Billing] Make procedures required by custom Usage Data Connectors accessible

Describe the issue

When one wants to implement a custom Usage Data Connector using the interface "Usage Data Processing", one needs to create an implementation of the procedure CreateBillingData(var UsageDataImport: Record "Usage Data Import"). However, all necessary procedures for creating billing data are internal and not accessible to a dependent app.

Proposed Change

Remove the internal keyword from the following procedures in UsageDataBilling.Table.al :

• internal procedure SetReason(ReasonText: Text)
• internal procedure InitFrom(UsageDataImportEntryNo: Integer; SubscriptionHeaderNo: Code[20]; ProductID: Text[80]; ProductName: Text[100]; BillingPeriodStartDate: Date; BillingPeriodEndDate: Date; NewQuantity: Decimal)
• internal procedure AlignContractCurrency(TempSubscriptionLine: Record "Subscription Line"; ImportCurrencyCode: Code[10])
• internal procedure CalculateAmounts(UsageDataSupplier: Record "Usage Data Supplier"; ImportCurrencyCode: Code[10]; NewUnitCost: Decimal; NewCostAmount: Decimal; NewUnitPrice: Decimal; NewAmount: Decimal)
• internal procedure UpdateRebilling()
• internal procedure InsertMetadata()

As well as the following procedure in CreateUsageDataBilling.Codeunit.al

• procedure CollectServiceCommitments(var TempServiceCommitment: Record "Subscription Line" temporary; ServiceObjectNo: Code[20]; SubscriptionEndDate: Date)

Expected behavior

Dependent Apps can access all procedures necessary for their own billing data creation which is necessary for custom Connectors.
