Working With Ansible Service Handler

Our setup-lb.yml & setup-app.yml playbooks restart apache service whenever will run the playbook even there are no changes made it
We can avoid getting apache service restart we can use service handlers
Modify your playbook accordingly setup-app.yml & setup-lb.yml
Lets add one more playbook to check status of services
```
vim check-status.yml
```

Now lets stop apache service on our loadbalancer by:
