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

Bug Description

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.

After discussion on this bug, we've decided the best approach for cloud-init in the short term is to extend the OVF datasource to allow for setting datasource configuration options to allow merging from both VMWare IMC data and OVF user-data.

Such configuration would be provided in /etc/cloud/cloud/cloud.cfg.d/90_somename.cfg

Datasource:
  OVF:
      mergemetadata: true|false  # If true, merge metadata from any DataSourceOVF-supported source
      mergeorder: [ovf, vmware-tools]

The mergeorder above says that any vmware-tools(IMC) metadata will override any discovered duplicate configuration keys found in ovf.
