Allow package deletion for non-empty packages.

[jthomas]

Environment details:

IBM Bluemix (US-South)

Steps to reproduce the issue:

wsk package create service_package
wsk action create service_package/hello handler.js
wsk package delete service_package

Provide the actual results and outputs:

error: Package delete failed: Package not empty (contains 1 entity) (code 4577263)

What do you want to change?

I want the API to support removing packages which aren't empty.

I understand this behaviour could cause accidental delete issues and would like a flag force to enable this.

Why do you want this change?

Packages are a convenient mechanism to group functions, triggers and rules into "services".

Being able to remove a package and have the contents removed is a much faster way to handle removing services without having to manually issue the individual delete calls for each resource.

In the Serverless Framework integration, I'm going to starting using this packages to deploy "services". serverless/serverless-openwhisk#29.

Before updating a service, I need to clear out the current resources that might have been removed from the configuration file. When the user wants to remove a service, I'll need to delete all resources.

This will currently require a large amount of boilerplate code, retrieving all the package resources and firing off individual API calls.

That would be very helpful.

Currently we have to do several get actions request and delete action by action, before we are able to delete the package. That's working, but really not fast.

So such a force option would be very helpful.

Do you use the API or a client (wsk cli)?

I used the REST API, as we have automated processes, and it's part of our software to interact with OpenWhisk
