Implement diff check

[sagikazarmark]

Instead of always applying a configuration, calculate diff using the objectmatcher library.

Maybe we can take a look at https://get-kapp.io/ because they have a quite nice desired state and diff calculation. It would be good to know, whether this is easily transferable.

@sagikazarmark is this under development on your end? I'd be happy to try contributing it (either using objectmatcher or kapp), but I don't want to duplicate efforts

[sagikazarmark]

@danxmoran it's on my todolist, but not a top priority, so feel free to give it a try if you want.

For now, I would prefer using objectmatcher, but @icereed thanks for the link, we will definitely take a look at it.

Hi @sagikazarmark

I'm not really sure how this provider is supposed to work. But what I'm see'ing is not matching my expectations:

• I apply a horizontalpodautoscaler (hpa) through this provider
• I use kubectl edit hpa foo and change some things manually
• I then run terraform again, but it does not detect that anything changed. And does not re-apply blindly.

Should I open a separate bug ?
