Add hooks for external install & svc management

This adds defined anchor points for external modules to hook into the
software install, config and service dependency chain.  This allows
external modules to manage software installation (virtualenv,
containers, etc) and service management (pacemaker) without needing rely
on resources that may change or be renamed.
