Add OvfPlatform.py
Add OvfPlatform.py

This patch adds the OvfPlatform.py module.  This new module contains a few
functions to facilitate gathering the required information for the
PlatformSection in the environment file.

Portential future work items for this patch are:
1) Beef up the virtTypeIsAvailable to actually validate that the
particular virutalization technology is present on the host.
2) Gather additional information about the virtualization technology such
as vendor and version
