container device interface

 CDI (Container Device Interface), is a specification for container runtimes,
 to support third party devices.
 .
 CDI concerns itself only with enabling container to be device aware.
 Areas like resource management are explicitly left out of CDI (and is
 expected to be handled by the orchestrator). Because of this focus, the
 CDI specification is simple to implement and allows great flexibility to
 runtimes and orchestrators.
