VirtualMachine update to allow creation from snapshot image

[p3ck]

SUMMARY

VirtualMachine supports swapping an exisiting VM to use a snapshot. This update allows for it to create the VM from the beginning from a snapshot.

Also includes a small update to azure_rm_virtualmachine_info to report details on os_disk. Snapshot creation is only supported with managed disks.

I noticed a linting error where this variable could possibly be referenced without having been defined.
