need to check that creating a new host update both tables (HostMetric & playbook_on_stats) with right values

steps:

1. Create a new host and set it to be automated
2. Wait for it to appear in the `playbook_on_stats`
3. Assert it was included in the host metrics
4. Assert it has a unique host name
5. Assert it has the `first_automation` AND `last_automation` set to same value as playbook_on_stats
6. Assert it has `automated_counter` set to 1
7. Assert all other fields has default value.
