be more declarative

[sebgoa]

if we deploy a function that already exists kubeless fails.

kubeless function create foo ...
kubeless function create foo ...

We should be a bit more declarative like kubectl apply, for example I would like to see:

kubeless function update foo

Create the function and not fail if the function already exists.

This will help with continuous delivery.

And yes, I am aware that we can be declarative with kubectl apply if we stick the function in a k8s manifest.

cc/ @murali-reddy do you think you could hot fix kubeless update to also create a function if if does not already exists ?

[sebgoa]

Same thing with kubeless trigger create/update

Lets also be more declarative regarding the issue title - I would suggest

Make "kubeless function update" create the function and not fail if the function already exists to improve CI
