Review Comment:
Do we need to this flag ? is nt it implicit that if the element is of
configdrive, we need to prepare the drive at this point ?

Review Comment:
can we move this to any Utils class ? seems like a generic implementation
for merging Json arrays

Review Comment:
does it mean we are always expecting nics information everytime we build the
config drive ? prior to this PR it used to work without this information also
right! please correct me if I'm wrong here

Review Comment:
looks like this answers my previous question, we are adding the metadata per
nic right!
Another doubt here, I hope this won't break the existing config drive which
are already built before this PR changes ? for example after we start stop the
VM or when MS had to reapply the metadata to the VM in other case ?
