* Set `raw=True` when reading passwords from ConfigParser files.
The assumption is that no one is actually doing interpolation on the
password value, even if they may for other configuration values, and
passwords are far more likely to contain '%'.
* Add vmware_inventory as well.
This patch add new environment variables to oVirt dynamic inventory
to be consistent with all other oVirt modules:
OVIRT_URL
OVIRT_USERNAME
OVIRT_CAFILE
OVIRT_PASSWORD
Those variables are used as fallback if user don't specify a ini file,
with appropriate variables there.
