[Feature Request]: need to set a prefix for a NIC and disk used by a vm

[khaliddermoumi]

Description

I need to be able to set a prefix for an NIC and the disks when using the VM module. This is because my customer has a naming convention using prefixes, such as the one recommended by MS: Cloud Adoption Framework. So I must be able to set a prefix for the NIC name, and the disks.

This could be done easily by adding an optional parameter nicPrefix (set to '' as default), which gets prepended to the NIC name in code. Likewise with the disks.
