* Fix error handling in provider setup process
This update ensures that when 'enable-consolidated-billing' is on, any exception thrown during the Stripe customer or subscription setup process for the provider will block the remainder of the setup process so the provider does not enter an invalid state
* Refactor the way BillingException is thrown
Made it simpler to just use the exception constructor and also ensured it was added to the exception handling middleware so it could provide a simple response to the client
* Handle all Stripe exceptions in exception handling middleware
* Fixed error response output for billing's provider controllers
* Cleaned up billing owned provider controllers
Changes were made based on feature updates by product and stuff that's no longer needed. No need to expose sensitive endpoints when they're not being used.
* Reafctored get invoices
Removed unnecssarily bloated method from SubscriberService
* Updated error handling for generating the client invoice report
* Moved get provider subscription to controller
This is only used once and the service layer doesn't seem like the correct choice anymore when thinking about error handling with retrieval
* Handled bad request for update tax information
* Split out Stripe configuration from unauthorization
* Run dotnet format
* Addison's feedback
* Added offboarding survey response to cancellation when FF is on.
