Removed planned instances from initial agent state, and moved it to the instance discovery stage (RecoverInstanceStateTask)
Removed optimization to detect unreachable machines, since we are sure they are not started, need to devise a more robust plan after ping refactoring
Added assert limitation to the exepcted number of instances, on uninstall. Required since the new depoyment planner, marks max number of instances as terminated/cleaned regardless of planned number of instances
Refactored planner to use new orchestrator interface (commandlinetasks)
