Previously (prior to v1.6.2) the Azure ARM builder had two delete functions
one that would run before any of the StepDelete* types, and one on deployment template
cleanup. The refactored coded re-introduces the logic from the previously removed
step in v1.6.1 as the main delete logic for the whole deployment
template. Ensuring that all deployed items are deleted before trying to
remove any managed disks.
This change moves all the deletion logic into the
step_deployment_template#Cleanup function to ensure that dependent steps
are only called once the created deployment items (i.e
StepDelateAdditionalDisks) have been deleted.

Closes#10070
I've run into a few cases where running the full test suite for the ARM
builder would fail because of conflicting image names. This is a
workaround for now the bigger fix is to have the acceptance clean up any
created images.
Results before change
```
the managed image named testBuilderAccManagedDiskWindows-1603151855 already exists in the resource group packer-acceptance-test, use the -force option to automatically delete it.
