It would be great to have a command to delete the backend.

backend super command has only "copy" subcommand.
Backends can be created by importing the OpenAPI definition but it can't be deleted through a 3scale toolbox.
It would be great if the backend super command would implement subcommands for managing backends (list, create, delete, update, apply) but for my use case (creation of service by importing OpenAPI definition) deletion would be enough.
