Inline cloud-config into template definition

[degremont]

It could make template management easier if cloud init configuration could be declared directly into template definition, avoiding to manage several file for only one template. As both are using yaml syntax, this should not be very difficult.

Either you pick a new keyword for that (cloud-config? cloud-init?) or you keep the same one and detect if its value its a string or a dict.

centos:
  image: /my/image
  user-data:

    bootcmd:
      - cloud-init-per instance yumclean rm -f /etc/yum.repos.d/*
    packages:
     - vim
     - pigz
    ...
