> Currently when we save host-overrides configuration, we have to do PUT of the delta on each host.
> This is problematic if admin provides an exception to 100 hosts. This will require 100 PUT calls which is expensive. There is a bulk update mechanism, but that requires the same content for all 100 hosts. This will not be the case if any hosts have other properties that are overridden.
> To save on network calls, we have to make one PUT call via the new API provided by AMBARI-1844.
