Accepting request 882190 from security:dehydrated

- Enable instantiated services (boo#1184165)

- Prepare instantiated service/timer support but not enable it:
  This seems to fail due to missing systemd support right now.
  So the only option at the moment is to copy the timer and unit
  file for a 2nd instance. Mark all files as part of dehydrated.target

- Rework support for /etc/dehydrated/postrun-hooks.d/:
  dehydrated.service nolonger starts them directly, the support was
  moved to a separate unit file. Please run:
  systemctl enable dehydrated-postrun-hooks.service
  to restore this functionality
- Run dehydrated as dehydrated user again

- Do not use the full path for config.d in the config files, which
  will simplify implementing multi instance support.

- Added more-examples.patch:
  Explain how we can have per certificate key algorithms

- Add directory where cleanup can archive unused certificates

+Postrun Hooks
+~~~~~~~~~~~~~
+
+dehydrated.service no longer starts scripts in /etc/dehydrated/postrun-hooks.d/
+directly, the support was moved to a separate unit file. Please run
+
+  systemctl enable dehydrated-postrun-hooks.service
+

+
+This change was required to ensure that the output of the dehydrated script stays
