Propagate ResourceGroup labels and annotations (#4165)
Browse files Browse the repository at this point in the history
* Propagate ResourceGroup labels and annotations

When I declare a ResourceGroup on disk, I expect the labels and
annotations defined on it to be propagated to the in-cluster inventory.
That was previously not the case.

kioutil annotations are removed (path, index, etc) since they are
redundant for inventories that are typically defined in one place, and
don't need to be reconstructed by a function pipeline.
