mismatch in object data structures for nutanix_vm and nutanix_vm_info (for example nic_list and disk_list).

[Yannick Struyf]

Consider following use-case:
I manually created a virtual machine in PC, but I want to change the powerstate.
In order to change the powerstate, I need to use the nutanix_vm module. This module requires following attributes that need to be passed in order to change the powerstate:
state, cluster, cpu, vcpu, disk_list, nic_list, memory

A user should use the nutanix_vm_info module to fetch these parameters but the data structures do not match for nic_list and disk_list.

disk_list returned via nutanix_vm_info:

If the data structures of both modules match, it will be a lot easier to fetch required information without additional parsing of data.
