##### SUMMARY
Some of the modules still return something in `ansible_facts`, even though the result in there is an empty list:
 - ~~`azure_rm_publicipaddress_info`~~
 - ~~`azure_rm_networkinterface_info`~~
 - `azure_rm_storageaccount_info`
 - `azure_rm_virtualmachineimage_info`
 - `azure_rm_virtualmachinescaleset_info`
 - `azure_rm_virtualnetwork_info`

Finally, `azure_rm_resourcegroup_info` always returns `ansible_facts` with content (which is also returned as non-`ansible_facts`).

When called as `_info` modules, these modules should not have anything in `ansible_facts` when returning.
