Feat: Enable skip delete import tf resource when destroy

[hoangndst]

What would you like to be added?

Option skip delete imported tf resource when destroying release.

Why is this needed?

When the imported tf resource is still used by another release, we need to retain it so that the release using that resource can function properly.

About this feature. I plan to add an IgnoreExternal field to the model Operator so from there the user can pass the command e.g. kusion destroy --ignore-external to the lower part to handle.
