Fixed CLOUDSTACK-2662 Preferred implicit dedication fails with insufficient capacity even if shared hosts are available. Issues: In Implicit planner resource usage is fixed to "Dedicated". It should be Dedicated/Shared depending upon the Implict Planner strict/preferred modes and hosts availability. Fixed: Issue is fixed by determining the resource usage to be "Dedicated/Shared" depending upon the Implicit strict/preferred mode and the hosts availability for the planner.
