CA-146592:  Change default search when in Infrastructure view

- If XenCenter node or a  disconnected host is selected, show the default search.
- Otherwise, find the top-level parent (= pool or standalone server) and show the search restricted to that.
- In the case of multiselect, if all the selections are within one pool (or standalone server), then show that report.
- Otherwise show everything, as on the XenCenter node.

CA-144708: Optimal server option doesn't seem to pass the Ronseal test
Based on the discussion of CA-144708, when error happens or the Current Server is listed and disabled
in the recommendation host list, there is no rating score and star actually, so it is good to hide the
zero star to avoid confusing.

This fix hides the zero star indication on XenCenter GUI.
