Merge pull request #5527 from mtnbikenc/installer-checkpoint

Automatic merge from submit-queue.

Installer checkpointing

This pull request adds an Ansible callback plugin to allow for 'checkpointing' the status of the OpenShift-Ansible installer.  The installer is divided up into phases and each phase will start with a status of 'Not Started'.  As the phase is performed the status will be updated to 'In Progress' and finally 'Complete'.  Should the install fail or complete successfully, the callback plugin will report the status of all phases after the PLAY RECAP.  The INSTALLER STATUS is also written to the Ansible log file.

Changes:
- Added installer_checkpoint role and callback plugin
- Added checkpoint 'Start' and 'End' plays to each installation phase

Additional items related to enabling proper checkpointing:
- Removed openshift_set_hostname and related task (related to 3.0)
- Added openshift-hosted entry point playbook
- Moved openshift metrics and logging out of openshift_hosted playbook
- Moved API Aggregation play to master install


Example playbook output:
