Add linuxkit metadata command

Browse Source 
Only subcommand is currently `create` which is a thin wrapper to create an iso
file in the format expected by `pkg/metadata`.

Currently very basic and just takes the content on the command line but could
be extended to read from a file etc.

# Metadata image creation
Run `linuxkit run` backends accept a `--data=STRING` option which will
cause the given string to be passed to the VM in a platform specific
manner to be picked up by the `pkg/metadata` component.
Alternatively `linuxkit metadata create meta.iso STRING` will produce
a correctly formatted ISO image which can be passed to a VM as a CDROM
device for consumption by the `pkg/metadata` component.
