Administrative Endpoint to Toggle Controller access

[YashoSharma]

It would be useful for admins to be able to enable/disable endpoints

• Endpoints to manage access to the controller
• DB table to store states of controllers (PK of controller name, and Bit for boolean)
• Cache the states on startup, and expire them when the state is changed
• If a state is not cached when accessed reread it from the db
• Middleware to process requests/handle invalid requests
• Use an EndpointNotAvailableError on failure

Is this toggling access to a controller or just a feature? It sounds like we'd want to toggle access to specific features ('create registration', 'update registration') not a specific API endpoint's controller ('registration').

To that end, would it make more sense to have a separate error for this? Something like FeatureNotAvailable? The UnprocessableRequestError is usually thrown for requests that cannot be processed for some general reason if I remember correctly.
