Support CDI devices in ctr --device flag

Browse Source 
This change adds support for CDI devices to the ctr --device flag.
If a fully-qualified CDI device name is specified, this is injected
into the OCI specification before creating the container.

Note that the CDI specifications and the devices that they represent
are local and mirror the behaviour of linux devices in the ctr command.
