Add endpoint and rabl nodes for IoP

[jeremylenz]

1. Add a scoped_search field, insights_uuid, so you can search hosts by their Insights UUID.
2. Add rabl nodes to the host list API response so you can see insights information. This included adding RABL infrastructure to foreman_rh_cloud, since it didn't use rabl previously.
3. Add an alias for insights_facet so I stop going crazy 😄
4. Add a new API endpoint, /api/v2/insights_advisor/host_details, which returns only Insights-related details about hosts.

I like the rabl + api work. But looks like we can do with a simpler host details controller for the advisors engine. So recommending changes.

-        before_action :find_organization
-
+        api :GET, "insights_advisor/host_details", N_('fetch host details given insights uuid')
+        param :host_uuids, Array, required: true
         def host_details
-          @hosts = ::Host::Managed.search_for(params[:search] || "", :order => params[:order]).where(:organization_id => @organization.id).includes(:insights)
+          uuids = params.require(:host_uuids)
+          @hosts = ::Host.joins(:insights).where(:insights => {:uuid => uuids })
           respond_to do |format|
             format.json { render 'api/v2/insights_advisor/host_details' }
           end
         end

No need to search as I initially thought we would. I just pass in a list of uuids that only insights and katello knows about.

@parthaa Thanks, updated!

I removed the search param from the controller. But didn't remove it from scoped_search since I don't see any harm in keeping it.

Works well
