Debug Output/Panic Output

N/A

Expected Behaviour

I would expect the application group to change the host pool it is pointing at.

Actual Behaviour

Host pool id is not updated on app group. It appears that this property is not editable and should be set to ForceNew in the resource code. The azure API for application groups also does not appear to have a field to update the host pool id.

Steps to Reproduce

1. terraform apply
2. Notice app group is pointing at pooledbreadthfirst host pool
3. Change app group host_pool_id to point at pooleddepthfirst host pool
4. terraform apply, notice TF detects the diff and applies change
5. Check azure portal and notice app group is still pointing at pooledbreadthfirst
6. Rerun terraform apply and see same diff in step 4
