Issue : #107, indirectly #13

Now, it is a bit easier to label both the created object (e.g. jobs) and its sub-templates (e.g. pods in jobs):

kopf.label(job, {'parent-name': name}, nested=['spec.template'])

Also, few tests added on the utility functions used internally, just to be sure they work as expected.

The auto-guessing on which sub-fields are templates, which are not (as suggested in #107) is skipped for now — that might require enumerating the kinds&fields from the docs.
