Notification: Notification handler for ovirt notification

  Added a new notification handler to notify nagios events
to ovirt. A new contact ovirt is added with the handler
which can sent events/alerts to ovirt engine using
Rest API. By default all gluster related configuration
entities like host, volume, gluster, bricks will have this
contact.

  By default contact ovirt will have some default values for
ovirt engie rest api and user fields. User has to fill the
right values in ovirt contact defined in gluster-contacts.cfg
file. Ovirt password has to be configured as a user variable
$USER3$ in file /etc/nagios/private/resource.cfg. User variable
$USER3$ used in command to pass the password to the handler.
