In case the kernel sends message back containing attribute not defined
in family spec, following exception is raised to the user:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do trap-get --json '{"bus-name": "netdevsim", "dev-name": "netdevsim1", "trap-name": "source_mac_is_multicast"}'
Traceback (most recent call last):

~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^

Introduce a command line option "process-unknown" and pass it down to
YnlFamily class constructor to allow user to process unknown
attributes and types and print them as binaries.
