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.

https://trello.com/c/VNEvT2Fo

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:
```

+OpenShift-Ansible Installer Checkpoint
+======================================
+
+A complete OpenShift cluster installation is comprised of many different
+components which can take 30 minutes to several hours to complete.  If the
+installation should fail, it could be confusing to understand at which component
+the failure occurred.  Additionally, it may be desired to re-run only the
+component which failed instead of starting over from the beginning.  Components
+which came after the failed component would also need to be run individually.
+
+Design
+------
+
+The Installer Checkpoint implements an Ansible callback plugin to allow
+displaying and logging of the installer status at the end of a playbook run.
+
+To ensure the callback plugin is loaded, regardless of ansible.cfg file
+configuration, the plugin has been placed inside the installer_checkpoint role
+which must be called early in playbook execution. The `std_include.yml` playbook
+is run first for all entry point playbooks, therefore, the initialization of the
+checkpoint plugin has been placed at the beginning of that file.
+
+Playbooks use the [set_stats][set_stats] Ansible module to set a custom stats
+variable indicating the status of the phase being executed.
+
+The installer_checkpoint.py callback plugin extends the Ansible
+`v2_playbook_on_stats` method, which is called at the end of a playbook run, to
+display the status of each phase which was run.  The INSTALLER STATUS report is
+displayed immediately following the PLAY RECAP.
+
+Phases of cluster installation are mapped to the steps in the
+[common/openshift-cluster/config.yml][openshift_cluster_config] playbook.
+
+To correctly display the order of the installer phases, the `installer_phases`
+variable defines the phase or component order.
+
+```python
+        # Set the order of the installer phases
+        installer_phases = [
+            'installer_phase_initialize',
+            'installer_phase_etcd',
+            'installer_phase_nfs',
+            'installer_phase_loadbalancer',
+            'installer_phase_master',
+            'installer_phase_master_additional',
+            'installer_phase_node',
+            'installer_phase_glusterfs',
+            'installer_phase_hosted',
+            'installer_phase_metrics',
+            'installer_phase_logging',
+            'installer_phase_servicecatalog',
+        ]
+```
+
+Additional attributes, such as display title and component playbook, of each
+phase are stored in the `phase_attributes` variable.
+
+```python
+        # Define the attributes of the installer phases
+        phase_attributes = {
+            'installer_phase_initialize': {
+                'title': 'Initialization',
+                'playbook': ''
+            },
+            'installer_phase_etcd': {
+                'title': 'etcd Install',
+                'playbook': 'playbooks/byo/openshift-etcd/config.yml'
+            },
+            'installer_phase_nfs': {
+                'title': 'NFS Install',
+                'playbook': 'playbooks/byo/openshift-nfs/config.yml'
+            },
+            #...
+        }
+```
+
+Usage
+-----
+
+In order to indicate the beginning of a component installation, a play must be
+added to the beginning of the main playbook for the component to set the phase
+status to "In Progress".  Additionally, a play must be added after the last play
+for that component to set the phase status to "Complete".  
+
+The following example shows the first play of the 'installer phase' loading the
+`installer_checkpoint` role, as well as the `set_stats` task for setting
+`installer_phase_initialize` to "In Progress".  Various plays are run for the
+phase/component and then a final play for setting `installer_hase_initialize` to
+"Complete".
+
+```yaml
+# common/openshift-cluster/std_include.yml
+---
+- name: Initialization Checkpoint Start
+  hosts: localhost
+  connection: local
+  gather_facts: false
+  roles:
+  - installer_checkpoint
+  tasks:
+  - name: Set install initialization 'In Progress'
+    set_stats:
+      data:
+        installer_phase_initialize: "In Progress"
+      aggregate: false
+
+#...
+# Various plays here
+#...
+
+- name: Initialization Checkpoint End
+  hosts: localhost
+  connection: local
+  gather_facts: false
+  tasks:
+  - name: Set install initialization 'Complete'
+    set_stats:
+      data:
+        installer_phase_initialize: "Complete"
+      aggregate: false
+``` 
+
+Each phase or component of the installer will follow a similar pattern, with the
+exception that the `installer_checkpoint` role does not need to be called since
+it was already loaded by the play in `std_include.yml`.  It is important to
+place the 'In Progress' and 'Complete' plays as the first and last plays of the
+phase or component.
