Automatic merge from submit-queue.

Add execution times to checkpoint status

This PR adds execution times to the checkpoint status report at the end of an installer playbook run.

- Checkpoint plays now use `all` host group to avoid using an undefined host group during the Initialization phase as well as maintaining the need to collect inventory vars for host group conditionals
- `run_once: true` is used to limit the execution to only one host
- `installer_phase_*` data is now stored as a dict so multiple data points can be stored for that phase
- Documentation updated


```
