[Darga] Upgrade to ovirt 0.11.0

[jhernand]

Purpose

This PR updates the oVirt provider to use version 0.11.0 of the ovirt gem, as that is necessary in order to calculate correctly the ems_ref attributes of inventory items retrieved from version 4 of oVirt.

Note that the commit in this PR was already part of another PR merged to the master branch, but that can't (I guess) be back-ported to the darga branch, as it contains other changes shouldn't be back-ported.

This PR is part of the fix for the following bug:

• Inventory refresh doesn't work with version 4 of oVirt

@chessbyte, @bdunne, @Fryguy, I'm not sure how you handle this situation: need to backport part of a PR that has been merged to the master branch. What I did is apply the required patch (cherry-picked the patch that @bdunne created, no change) from that PR, and create a new PR, based on the darga branch. Let me know if this is OK, or if you want to do it different.

Note also that I don't have permissions to add labels, so I can't add darga/yes.

@gmcculloug Note that this is a PR direct to darga and should only be merged by @chessbyte

@jhernand I don't think you can bundle without all of the changes included in the original PR. I think we have to mark it as darga/yes.
