Description:
This callback will be applied by util.mount_cb() on the mounted
file.
Deltacloud file name contains deltacloud. Those not using
Deltacloud but instead instrumenting the injection, could
drop deltacloud from the file name.
Input:
mount_dir - Mount directory
Returns:
User Data

CLOUD_INFO_FILE or
the dmi data.

'RHEV', 'VSPHERE' or 'UNKNOWN'

Description:
User Data is passed to the launching instance which
is used to perform instance configuration.
Cloud providers expose the user data differently.
It is necessary to determine which cloud provider
the current instance is running on to determine
how to access the user data. Images built with
image factory will contain a CLOUD_INFO_FILE which
contains a string identifying the cloud provider.
Images not built with Imagefactory will try to
determine what the cloud provider is based on system
information.
