pre/post update - pretty print scripts that were ran along with success/failure

[nmaludy]

When running the patching::pre_update and patching::post_update it would be nice to pretty-print all of the hosts and what scripts were actually execute on each one (maybe there are customizations in there) along with success/failure.

Thinking the output could look something like:

Pre-update script executions:
- name: centos.domain.tld
  script: /opt/patching/bin/pre_update.sh
  status: success
- name: centoscustom.domain.tld
  script: /my/custom/path/blah.sh
  status: success
