Fix incorrect path for Kustomize in addon operators

[rajansandeep]

Kustomize cannot find the kustomization.yaml file for creating the final manifest.

The error before this fix:

This PR fixes the error and also updates the test to reflect the case where an operator uses Kustomize

@rajansandeep
Thank you to create PR! 🎉

This PR changes private "Reconciler.options" with public "Reconciler.Options", I know the reason do that.
"reconcilerParams.kustomize" is also same.

But, we should minimize a range which can access to variable, I think.
It may need some refactorings in Reconciler functions.
Could you do that?

@justinsb
WDYT?

Thank you @rajansandeep !

I think @atoato88 's feedback was addressed by the getter. I think this is a good approach. Please raise if that didn't solve it.
