Issue description

While doing the exercise , made a mistake of using the inventory.sol file , which does not have the group names starting with a capital letter. Since the names are case sensitive, the initial grading completely fails. 

rectified the inventory file to change the names of cities to begin with uppercase letter.
then stage,commit,synced with repo.  

Synced inventory on ansible controller steps 4.1 to 4.5 , and this time the grading fails with group names Singapore and Raleigh 

Additional Note - important :

On a side-note , one of our internal RH users have submitted a ticket concerning 
ch02s07 - service now ticket number RHT2170807 , where the user says :

" In the lab operations-review, the instructions tell us to update the inventory "Demo Inventory", but what is checked on the grading playbook is the "Dev" inventory. "
