This adds a command for deleting ImagePolicy objects. Since the control flow for the command needs only a runtime.Object (and a name for the type), it can be factored out. I have made the argument (field in the deleteCommand struct) an interface `objectContainer`, through which the command code gets a `runtime.Object` to deserialise into (and delete). It could be simply a `runtime.Object` here; however things like `getCommand` require other methods, so it's convenient to have an interface for it.
