Interface ResourceNameAvailability

If reason == invalid, provide the user with the reason why the given name is invalid, and provide the resource naming requirements so that the user can select a valid name. If reason == AlreadyExists, explain that resource name is already in use, and direct them to select a different name.

true indicates name is valid and available. false indicates the name is invalid, unavailable, or both.

Invalid indicates the name provided does not match Azure App Service naming requirements. AlreadyExists indicates that the name is already in use and is therefore unavailable. Possible values include: 'Invalid', 'AlreadyExists'
