Title: Let apt_repository modify existing apt repos

This lets the `apt_repository` provider modify existing apt repositories as described in gh-8.

In order to do this, I modified the key fetching mechanism in such a way that keys are only retrieved if necessary.

Also, `updated_by_last_action` is now called only if:

* a new key had to be retrieved
* a repo file was changed

Feedback welcome!
