> Orchestration via UpgradeHelper need to orchestrate via HOSTS instead of the UpgradePack services.  This will entail:
> * Refactor UpgradeHelper to choose orchestration model
> * Upgrade Pack changes are minimal, StageWrapper and Manual tasks are generated in-code.
> * Determine service check changes (if any)
> * HostGrouping should use the following stages per-host:
> *# Stop command for each component
> *# Manual message to ask to proceed
> *# {{install_packages}} task - ONE per host.  The purpose is to make sure all the symlink logic already in place is called correctly
> *# START commands for daemons, INSTALL commands for clients, just as a new cluster would do.
