Rename a lot of core classes to match the correct naming scheme of the library

[remi-stripe]

Took the opportunity to rename a lot of older classes that were never prefixed, paving the way for the release of the codegen-ed library in the next few months.

List of changes:

• Renamed the class Fee to BalanceTransactionFee on BalanceTransaction
• Renamed the class Outcome to ChargeOutcome on Charge
• Renamed the classes Evidence to DisputeEvidence and EvidenceDetails to DisputeEvidenceDetails on Dispute
• Renamed the class OutcomeRule to Rule and moved it to the Radar namespace
• Renamed the classes ShippingMethod to OrderShippingMethod, StatusTransitions to OrderStatusTransitions and DeliveryEstimate to OrderShippingMethodDeliveryEstimate on Order
• Renamed the class Inventory to SkuInventory on Sku
• Fixed the type of NextPendingInvoiceItemInvoice on Subscription to be a DateTime?
• FraudDetails on Charge is now a class ChargeFraudDetails instead of a dictionary
• Removed Connect on the WebhookEndpoint resource as it is not supported

So. I wanted to flag that one explicitly @ob-stripe.
It's quite an old property but, if I am not mistake, this should be a real API resource with an object field since this is expandable on Charge.outcome.rule. Really curious what your thoughts are here?

[ob-stripe]

Strictly speaking we don't need the object field if the expandable field is not polymorphic. But AFAIK this is the only case of an expandable field where the expanded object is not an API resource with an object field.

I don't think it's worth fixing, but we should discuss this internally to decide if this is something we'd want to allow on other API resources in the future.

[remi-stripe]

The reason I'm asking is that, if we added object later the class would have the object value as a name. When right now it's kinda ChargeOutcomeRule and in a way it's annoying

[remi-stripe]

Do you think we should call this one Rule in the Radar namespace in that case so that in the future, if we add object it will likely be object: "radar.rule"?

[ob-stripe]

We should do the same thing as stripe-java to facilitate future codegen, so yes, ChargeOutcomeRule should be renamed to Rule in the Radar namespace: https://github.com/stripe/stripe-java/blob/master/src/main/java/com/stripe/model/radar/Rule.java. (Thanks for checking!)

[remi-stripe]

Fixed, PTAL

[ob-stripe]

@remi-stripe Should we close this for now?

[ob-stripe]

I've reset the integration-v36 branch, so you'll need to rebase to remove the extra commits.

@ob-stripe Re-assigning to you for review again. Flagging I fixed another issue raised by @clement911 in #1969 (comment)
