Refactor topology usage

This commit intends to simplify and disentangle
the deployment of components from their registration
and key syncing.

* Component recipes no longer require knowledge of their topology
  and do not sync keys.
* The key-sync recipe has been added to perform key sync. It can
  be run on any component.
* Keys are no longer stored in node attributes on all components.
  Only the CLC for each environment has the keys.
Copy into place the policy kit file for NC
