OVF does not read user-data if vmware IMC is used.

As currently implemented, cloud-init will read either OVF CDrom *or* the vmware IMC data.

That means if user-data is provided in the OVF environment file then it will not be consumed at all by cloud-init.

It seems we need to either:
 a.) support reading and merging these two sources of information
 b.) provide some way to feed user-data through the IMC path separately.
