For these kind of settings to be applied on nodes, I think Duffy API
could allow user specifying a file location containing a cloud-init
configuration, or a kickstart snippet, or a raw shell script to be executed.

For example:

$ cico node get --arch ppc64le --release 7 --count 1 --post-setup

$ cico node get --arch ppc64le --release 7 --count 1 --post-setup

$ cico node get --arch ppc64le --release 7 --count 1 --post-setup

So all the customization is delegated to the user. Duffy would just need
to know if it has to run cloud-init, kickstart, or shell script.

A benefit of allowing cloud-init configuration is that users from
OpenStack would need very few or none effort to update their cloud-init
settings to use with Duffy.
