The tests were removed due to a nil pointer panic in
testCheckAzureRMVirtualMachineOSDiskVHDExistance when the storage account itself
had been deleted in the destroy stage
Added a test to cover opting out of VHD delete rather than polluting the basic
linux VM test.

* provider/azurerm: destroy azurerm_virtual_machine OS Disk VHD on deletion
The OS Disk previously wasn't deleted with the VM, this causes subsequent
apply operations which recreate the VM to fail as the VHD blob already exists.
Fixes#6610
* provider/azurerm: add delete_os_disk_on_termination to azurerm_virtual_machine
delete_os_disk_on_termination is a bool which defaults to false to avoid making
a breaking change, and to follow the same flow as the Azure API
When using winrm config block, we had an address issue. This is no
longer a set but a list (As a list fits it more approp)

Fixes#7053 where, when using `additional_unattend_config` in
`os_profile_windows_config` we got an error as follows:
```
azurerm_virtual_machine.test: [DEBUG] Error setting Virtual Machine
Storage OS Profile Windows Configuration: &errors.errorString{s:"Invalid
address to set: []string{\"os_profile_windows_config\", \"1534614206\",
\"additional_unattend_config\"}"}
```
adminPassword
The Azure API never returns the AdminPAssword (as is correct) from the
Read API call. Therefore on Create, we do not set the AdminPassword of
the vm as part of the state. The Same func is used for Create & Update,
therefore when we changed anything on the VM, we were getting the
following error:
```
statusCode:Conflict
serviceRequestId:f498a6c8-6e7a-420f-9788-400f18078921
statusMessage:{"error":{"code":"PropertyChangeNotAllowed","target":"adminPassword","message":"Changing property 'adminPassword' is not allowed."}}
```
To fix this, we need to excldue the AdminPassword from the Update func
if it is empty
