From 4c1b0dd4ab8f3a5d4fcfa4ba1501ed374793e77a Mon Sep 17 00:00:00 2001

Subject: Refactor upgrade playbook(s)

- Split playbooks into two, one for 3.0 minor upgrades and one for 3.0 to 3.1
  upgrades
- Move upgrade playbooks to common/openshift/cluster/upgrades from adhoc
- Added a byo wrapper playbooks to set the groups based on the byo
  conventions, other providers will need similar playbooks added eventually
- installer wrapper updates for refactored upgrade playbooks
  - call new 3.0 to 3.1 upgrade playbook
  - various fixes for edge cases I hit with a really old config laying
    around.
  - fix output of host facts to show connect_to value.
